The session HUD is FusionHUD (Bannerlator's HUD) with every reading taken from
the same source, and worked out the same way, as the MangoHud build that runs
Steam's performance overlay in a DroidDeck session.
- gamescope patch 0125 (gamescope-3.16.29-p19) shares the frame times that
mangoapp reads (one per signalled commit of connector 0) in a ring named by
DROIDDECK_HUD_FRAMES; the app reads it once per display frame and counts the
compositor's frames when gamescope sends none.
- MangoHud's rules: FPS over periods of at least 500 ms, frame time = 1000/FPS,
200-frame graph on a fixed 0-50 ms scale; CPU, GPU, temperatures, RAM, swap,
VRAM and battery from MangoHud's sources. Zones 22/26/28 are typed as GPU and
DDR sensors, so Steam's overlay CPU temperature no longer includes them.
- Five sizes in a panel shaped like the DroidDeck mark, with a centred header,
one left edge, neon outline and FPS; Minimal is the default size. Settings on
a new "Performance HUD" drawer page, with Bannerlator's options.
- The HUD reads sensors and polls frames only while it is drawn (not while
hidden, in picture-in-picture or behind another app), keeps its place after
picture-in-picture, and the diagnostics export has its own reader.
Device-tested on the AYANEO Pocket FIT: same readings as Steam's overlay side
by side in Dead Cells; the HUD updates in a game, hides in picture-in-picture
and comes back in place, no crashes.
0123 backports upstream 0efe47c and 666c52b by Matthew Schwartz (commit
completion list lifetime, no Rc to a dying commit). 0124 polls a new
commit's fence at import; a finished frame is marked done at once and
handled in the same steamcompmgr pass instead of a second wake through
the image waiter. commit_ready_check (default on) turns it off.
Pins gamescope 3.16.29-p18 (0123 + 0124). On the AYANEO Pocket FIT about
81 % of commit fences are ready at import; gamescope-xwm 22-26 % -> 16 %
of a core, gamescope_img 10-11 % -> under 2.5 %.
The WSI layer sends override_window_content on every present, and
gamescope walked the X tree to the top-level window (a blocking
XQueryTree round trip per level, under the wlserver lock) before
noticing the same swapchain already overrides it. A swapchain repeating
the same window now skips the walk for 100 ms (0121).
Backport of upstream gamescope 2962992 by Matthew Schwartz: the nested
Wayland backend's input thread reads the host display, but steamcompmgr
does not watch that fd, so buffer releases and presentation feedback
could wait up to one refresh for its next poll; the input thread now
wakes it after each read (0122).
Pins gamescope-3.16.29-p17, the archive that was A/B-tested on the
device. PATCHES.md also describes the p16 change to 0120.
Remove the Performance mode switch. The session always runs the way
Performance mode did: replaced buffers go back to the game at once
(except while mirroring to glasses), gamescope's WSI layer and winex11
reuse their per-present window checks, and games get eight swapchain
images while uncapped. Steam's Frame Limit in the Quick Access menu is
the only limit.
gamescope 3.16.29-p15 (p14 plus two patches):
- 0119: with the Frame Limit on, gamescope forces FIFO while the WSI
layer hands the driver MAILBOX, so a game with eight images could
queue up to seven frames ahead of the screen. While the limiter forces
FIFO the layer uses its default of 3 images; DXVK and VKD3D-Proton
recreate their swapchain when the limiter changes, other apps are asked
to with VK_SUBOPTIMAL_KHR.
- 0120: -r fixed gamescope's pacing and limiter rate for the whole
session. With GAMESCOPE_NESTED_REFRESH_FOLLOWS_HOST=1 a rate the host
has reported for 300 ms replaces it (a switch from 144 to 120 Hz passes
through 72 Hz for a few frames), and Steam gets the display information
again. The session sets it whenever it passes -r.
Steam keeps its Frame Limit as the client setting
gamescope_app_target_framerate and offers the values gamescope's display
state lists. After a refresh change, a limit the new rate does not offer
(72 at 120 Hz) left the slider on its first value while the game kept the
old limit. The Steam helper watches the offered values and, once they
settle, keeps the limit when it is still offered and moves it to the
highest value otherwise, through Steam's own setting so the slider shows
it. Steam's webpack does not expose its module cache, so the gamescope
service is found by the calls its module makes, and the helper retries
the install every 10 s until Steam is ready.
The session window asks for the fastest mode the peak refresh setting
allows and chose again only when the display changed, so after it had
asked for 60 Hz, raising Android's refresh setting left the display,
gamescope and the limit at 60. It now also chooses again when
peak_refresh_rate or min_refresh_rate changes.
Adds a Performance mode switch under Mode settings > Frame rate, off by default and stored per mode like the frame limit. Off keeps today's behaviour. On:
- with no frame limit, the compositor hands buffers back to the game as soon as they are replaced instead of once per refresh, and gamescope's WSI layer is asked for at least 8 swapchain images; a chosen frame limit still paces
- DROIDDECK_WSI_BYPASS_CHECK_MS=100 lets gamescope's WSI layer reuse its present-time Xwayland bypass check (patch 0117, gamescope-3.16.29-p13); WINE_OFFSCREEN_CHECK_MS=100 does the same for winex11 once a DroidDeck-Proton release carries that fix. Off sets both to 0.
The gamescope pack now ships the patched WSI layer and SessionFiles stages it over the runtime's stock copy. Two per-game options, off by default: PROTON_DXVK_D3D8 and WINE_D3D_CONFIG renderer=vulkan|gl.
AIO Graphics Test on an AYANEO Pocket FIT (Adreno 750), off -> on: Vulkan 204 -> 1787, OpenGL 296 -> 2169, D3D12 308 -> 3563, D3D11 1133 -> 2874, D3D9 1253 -> 3098 fps; DiRT Showdown 92.2 -> 93.4 (GPU-bound).

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.
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.
In touchpad mode the cursor moved but Big Picture highlighted nothing and a tap-to-click
selected nothing: the nested pointer's motion reaches wlserver as touch 0, and in Passthrough
(the touch mode Big Picture sets) a motion for a touch that is not down moves nothing, so the X
pointer stayed where it was. 0111 passes bAlwaysWarpCursor, as the other touch modes already warp.
3.16.29's Wayland backend bound only wl_pointer and wl_keyboard; touch from DroidDeck's
compositor was never read, so Steam could not be touched. 0110 binds wl_touch in the input
thread and feeds each finger to wlserver_touchdown/touchmotion/touchup, the Steam Deck
touchscreen's path, so Big Picture's Passthrough touch mode gets real touches.
Four of Armada's patches apply to 3.16.29 as they are (appid-focus fallback, ARM64 night mode,
ARM64 colour-temperature slider, P3 red); two more are ported by hand: realtime-priority Vulkan
queues on GAMESCOPE_FORCE_VULKAN_REALTIME=1 without CAP_SYS_NICE, and the gamepad cursor sprite
following the X pointer. build-gamescope.yml builds Arch Linux ARM's package with them in an
Arch container, checks every NEEDED library against the runtime's own list, and publishes the
binary as a release asset for the apk to stage over /usr/local/bin/gamescope.
