The client reads config.vdf once, as it starts. A title installed during a
session got its per-app ARM64 Proton entry from the compat beat, but the
running client kept its own pick: native for a Linux build, which then sat
on "Downloading content (0%)" waiting for Steam Linux Runtime 2.0 and FEX
it can never run here (Left 4 Dead 2), or proton-stable for a Windows one.
The beat now runs the compat pass with --live, which notes titles it maps
while the client runs. Once each has finished installing and no game is
running, the session restarts the client through the existing restart-once
marker. Once per title and three times per session at most. The mapping is
re-applied before the client starts again, since it writes config.vdf back
from memory as it exits.
A Source-engine game says whether it started VAC-secure only in its own
console, which reaches a file only with -condebug. With the new Setup
toggle on (off by default), the launch wrapper adds -condebug to Source
and Source 2 titles and notes each launch; at the end of the session each
console.log written during it is copied, scrubbed, into vac/ and vac.txt
quotes the game's secure/insecure lines, any VAC lines in the client's
logs and which client builds are on disk. No connection to a server is
reported as inconclusive rather than guessed.
* Add your own apps to the Desktop page
An Add tile on Desktop takes a .sh script, an AppImage, a GitHub repo
(newest ARM64 AppImage release) or a Flatpak ID, with an optional name
and icon. Script folders are linked into the session, or copied when
they hold Linux programs (shared storage is noexec); folders outside
internal storage are bound at their own path.
Each app's page opens it under gamescope, edits its name and icon (with
icons suggested from its GitHub repo), checks a GitHub app for a newer
release and updates it in place, or removes it. Replaces the beta
AppImages section.
* Put Add at the end of the installable emulators
Installed emulators and added apps keep the top section, shown once there is one. Add closes the installable grid, or the installed one when nothing is left to install.
* Import DwarFS AppImages and their SVG icons
uruntime images built with sharun keep one program under several names
as hard links, which Android denies apps, so dwarfsextract aborted. The
extraction runs with proot's link2symlink, and each linked name becomes
a file of its own afterwards; their AppDir is followed through the
squashfs-root link.
An image's icon is a PNG of at least 128 px from the name its entry
gives, else its SVG (drawn with AndroidSVG), else the largest PNG, else
.DirIcon.
* Give AppImages the session's pads
sharun images start the app through their own ld.so, patched not to read
/etc/ld.so.preload, and drop LD_PRELOAD unless allowed, so the app never
loaded libfakeinput and saw no controller. The launcher now hands the
preload list over in LD_PRELOAD with SHARUN_ALLOW_LD_PRELOAD set.
Pad defaults also put Player 1 on the controller for yuzu-family
emulators, once, while it is still on the keyboard.
* Redesign the Add and Edit app dialogs
Source and appearance sit in two panels side by side, with a live
preview of the Desktop tile. A disabled primary button keeps an outline
so it still reads as a button.
Preload library answers stat/open/access/readlink in-process via a
trampoline page proot 0014 lets through seccomp. On by default with a
Performance toggle; also sets GLIBC_TUNABLES rseq=0 and malloc top_pad.
* fix: carry the installed Steam build into imported games so Steam stops re-verifying them
A second-library game downloaded by WinNative was registered with a bare
manifest (no buildid or InstalledDepots), so Steam treated it as build 0 and
verified all ~92 GB of Final Fantasy XV through proot. Reuse WinNative's
.winnative-steam manifest, or a completed .DepotDownloader/depot.config, so
Steam only fetches what changed since the recorded build.
* fix: give queued Steam fresh installs of imported games the recorded build
Steam rewrites a bare import manifest into a fresh install at build 0
before downloading anything. While nothing is downloaded or staged, the
WinNative build is still safe to carry over, so Steam skips the full
re-download (FF7 Remake was queued for 98 GB this way).
* fix: mount the game storage at /mnt/droiddeck-sd
The second library was bound at /mnt/bannerlator-sd, a name left from the
Bannerlator port, which is what Steam shows in its paths and errors. Bind
it at /mnt/droiddeck-sd, keep the old path as an alias for links and
prefixes that still name it, move Steam's library entry in place, re-point
import links, read ownership snapshots taken under the old path, and key
added-game shortcut ids by the old path so their prefixes stay put.
* fix: restart Steam once when owned added games are confirmed
On a fresh install the importer runs before any ownership snapshot exists,
so every added game became a non-Steam shortcut and stayed one until the
client happened to restart. Once the watcher confirms owned titles that are
not imported, it asks the session for one restart, while no game runs and
no download is in progress, and the importer turns them into Steam entries.
* perf: answer Turnip's zero-timeout KGSL timestamp polls without blocking
Turnip polls a timeline point with IOCTL_KGSL_DEVICE_WAITTIMESTAMP_CTXTID
and a timeout of 0, which KGSL reads as wait forever; Mesa does it under
a lock on every signalling submit, so vkd3d-proton, DXVK, gamescope and
Zink ran in lock-step with the GPU. The session preload now answers
those polls from the context's retired timestamp and passes everything
else to the kernel. Bannerlator measured a D3D12 demo at 614 -> 4335 fps
with the same answer in its Vulkan adapter. BL_NO_KGSL_POLL_FIX=1 turns
it off.
* perf: frame limiter, live panel refresh, opt-in GPU clock pin, cheaper cursor sync
- A per-mode frame limit (Steam and desktop settings, off by default):
gamescope's -r, the compositor's buffer-release pacer, the display
layer's frame-rate vote and a panel mode the cap divides evenly, as
WinNative's per-shortcut limit does. BL_FPS was always 0 and the
pacer's limit was never set.
- The compositor follows the panel's refresh rate when it changes
mid-session instead of reporting the rate read at start. (WinNative.)
- Performance > GPU: hold the Adreno clock at its top through KGSL's
power-control property, no root (Bannerlator's PerfGpuTurbo). Off by
default; cleared when the session stops and at the next app start if
a killed process left it set.
- The cursor image is copied across JNI only when its serial changes,
not on every pointer move.
* perf: stop re-seeding every prefix every 5 s, and run the library helpers only on change
- bannerlator-seed-redists stamped its change check from a block that
carried the current time, so it never matched: every prefix had ~32
keys appended to system.reg on every beat. The stamp now comes from
the names; Proton's prefix template is seeded too (date kept), with
WinNative's built-in list until the client has the install scripts.
- The library beat runs the seeder every 15 s and steam-compat only
when a directory it reads has changed, or once a minute.
- The client-core pin reads /proc itself and runs taskset -a only for
new processes or ones that grew threads.
- The games watcher backs off after a failed ownership probe and does
not probe while a game runs.
- The Proton launcher runs the newest ARM64 depot by build number, and
PROTON_USE_PIPEWIRE defaults to 0. (WinNative.)
* perf: Mesa's database shader cache, and proot's tracer above the guest
- MESA_DISK_CACHE_DATABASE=1 for the session: the file cache opens a
file per lookup and opens and renames one per store, each a proot
stop; the database is opened once and used with pread/pwrite.
- proot's single tracer thread is raised to nice -6 (under the
compositor's -8) two seconds after it starts, so the first guest
process it forks keeps nice 0. setpriority() directly, not
Process.setThreadPriority, which would also move its cgroup.
* feat(lsfg): take Lossless Scaling from Steam by itself, import it once owned, rebuild on update
- Lossless.kt owns the DLL and its shader cache. The copy the Steam
client installs (runtime library or the card's) is taken by itself
and taken again when the client updates it (size/mtime stamp). The
DLL is copied in and built into a cache named after its SHA-256, so
a new DLL hands the compositor a new path; a build that fails keeps
the working cache. Builds are serialized.
- The Steam session asks the signed-in client once per session whether
the account owns app 993090 until the answer is yes, then records it
and the app stops asking (BL_LOSSLESS_OWNED). Once owned, the frame
generation menu offers "Import Lossless.dll…", on the main screen and
in the session drawer; an import stays until Steam's copy changes.
- The compositor restarts the LSFG engine when its cache path changes,
and a new engine selection clears an earlier start failure, so an
updated DLL or a retry no longer needs the app restarted.
- The HUD says when LSFG is waiting on Lossless Scaling instead of
"starting"; frame generation strings are resources.
- Removed LsfgNative's unused DLL variant and cache-match calls.
* Find Lossless.dll in added Games libraries too
* LSFG: 120, 90 and 60 fps targets alongside 2x-4x
The pacer's target-rate mode picks 0-3 generations per game frame. While it
is warm the input ring and shared chain follow every frame, so frames that
generate nothing don't leave the next one without history.

The Steam menu is an overlay that takes input without changing gamescope's focus
window. A fullscreen wine game minimizes itself when it loses input, and gamescope
only takes a window out of iconic when the focus window changes, so after Resume
the game stayed minimized: a black screen with its caption in the top-left corner
(Titanfall 2 on GE-Proton 11, proven on device).
gamescope patch 0112 remembers the iconify request and puts the window back to
NormalState before input returns to it, then hands focus over again so wine
restores and activates it. The session script also asks gamescope to restore the
game once input comes back from the client (GAMESCOPE_RESTORE_FOCUS_WINDOW);
BL_RESTORE_ON_RESUME=0 turns that off.
* perf: cache pinned downloads, skip unchanged proot rebuilds, and wait out a Docker Desktop restart in the local build
* perf: skip xalia and gamescope realtime queues by default, add a realtime toggle, default the mic off
* fix: show the saved Steam Deck mode on the Steam page before Performance has been opened
The gamepad-cursor port queried the X pointer on every vblank, a
blocking round trip to Xwayland on the paint thread. With no cursor
image the position comes from wlserver as upstream; while the cursor is
hidden for inactivity X is asked every 50 ms. The realtime-queue comment
now says it is a no-op on KGSL Turnip.
The session's watchers slept with sleep(1) and read files with cat, an
exec each under proot; they now wait in bash itself. steam-compat
writes its tool, the adopted wrappers and config.vdf only when they
change, the games watcher probes ownership when its matches change or
every five minutes instead of every 30 s, and Proton no longer inherits
the client's steamrtarm64 library path.
fake_id0 (loaded by -i for Xwayland's set*id) now traces only the set*id
family and the xattr fixups when the ids given are proot's own, and the
seccomp filter traces ioctl only for the termios and FICLONE requests
proot rewrites. The faccessat2 and statx exit stops are dropped on
kernels that have the calls.
* Add ownership-aware Steam game folder imports
* Fix Steam title lookup and installed game manifests

On a foldable's inner panel (Galaxy Z Fold8: 2448x1848, ~4:3) gamescope
is started with the nested size equal to the output, so games are asked
for the panel's own shape. Many cannot do it and letterbox themselves,
and gamescope's scaler has nothing to stretch. "Stretch games to fill
the screen" only forces window size, so it does not help.
New Steam setting "Stretch 16:9 games to a narrower screen" (off by
default): bannerlator-session then gives games a 16:9 surface at the full
output height (-w) and adds -S stretch, so they render at a shape they
support and fill the panel with no bars and no crop. An output that is
already 16:9 or wider is left untouched. Passed as
BL_GAMESCOPE_STRETCH_16X9 and listed in device.txt.
