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.

gamescope patches carried by the app
Built by .github/workflows/build-gamescope.yml on top of the exact gamescope the Linux runtime
ships (3.16.29, Arch Linux ARM's package, same build options), and staged from the apk over
/usr/local/bin/gamescope at each session start - the hosted runtime image is never touched.
The binary's shared-library needs are checked against runtime-sonames.txt, the runtime's own
library list, before anything is published.
0002-steamcompmgr-fallback-appid-focus.patch- Armada (armada-os/armada), verbatim.0009-fix-arm64-steam-night-mode.patch- Armada, verbatim: the ARM64 client packs the night-mode property differently; the slider did nothing.0019-steamcompmgr-arm64-virtual-white.patch- Armada, verbatim: the colour-temperature slider's (x, y) arrives as one 64-bit element from the ARM64 client; y is recovered from x.0020-color-p3-red-is-wide-gamut.patch- Armada, verbatim.0100-realtime-queue-and-gamepad-cursor.patch- this app, two of Armada's ported by hand onto 3.16.29: realtime-priority Vulkan queues on request (GAMESCOPE_FORCE_VULKAN_REALTIME=1) without CAP_SYS_NICE, which proot can never have (a no-op on KGSL Turnip, which has a single submit-queue priority); and the gamepad-driven cursor sprite following the X pointer that XTest moves (it sat frozen). The X pointer is asked for only while a cursor image is drawn - every vblank while shown, every 50 ms while hidden for inactivity - since each ask is a blocking round trip to Xwayland on the paint thread; with no image, wlserver's position is used as upstream does.0110-wayland-backend-touch.patch- this app: the nested Wayland backend bound only the host's pointer and keyboard, so a finger on the phone's screen never reached Steam. It now bindswl_touchtoo and hands each finger to wlserver's touch path (wlserver_touchdown/motion/up) - the one a Steam Deck's touchscreen drives - so what a touch does follows the client's touch mode (Steam's Big Picture sets Passthrough: a real touch, rows scroll under a finger). Finger ids are offset by one, since the nested pointer already moves wlserver's touch 0.0111-wayland-pointer-warps-in-passthrough.patch- this app: the nested pointer's motion goes to wlserver as touch 0, and in Passthrough (Big Picture's touch mode) a motion for a touch that is not down moves nothing - so in the app's touchpad mode the Steam client saw no hover and a click landed wherever the pointer had last been. The motion now always warps the real pointer as well (bAlwaysWarpCursor), which the other touch modes did already.0112-restore-iconified-game-on-resume.patch- this app: the Steam menu is an overlay that takes input without changing the focus window, and a fullscreen wine game minimizes itself when it loses input. gamescope only takes a window out of iconic when the focus window changes, and wine will not activate a window it believes iconic, so after Resume the game stayed minimized: a black screen with its small caption in the top-left corner (Titanfall 2, GE-Proton 11). The iconify request is remembered and the window goes back to NormalState before input returns to it, then focus is handed over again.GAMESCOPE_RESTORE_FOCUS_WINDOWon the root window asks for the same restore from outside (the session script's resume watcher).
Sixteen more of Armada's patches are DRM/lease/HDR-on-KMS work for a native display, which this app's Wayland-hosted gamescope never reaches, or need a newer gamescope than the runtime has.
