Tomb Raider I-III Remastered (OpenGL) under gamescope: crashed 3 s after its
window mapped, then (once past that) sat black with audio playing.

  • extra_libs-20261104.tzst: the guest libGL (Mesa xlib GLX on zink, the same
    file on X11 and gamescope) reported GLX_BUFFER_SIZE as the X visual's depth,
    24 on Xwayland against 32 on the in-app X server; the game's
    wglChoosePixelFormatARB needs 32 and got no format. GameNative/mesa#58 counts
    the emulated alpha channel. Same archive otherwise; the manifest entry's file
    name changes because the app caches archives by name.
  • payload 20261104.2: gamescope A33's startup blind lifted only on a commit from
    the Vulkan override surface; a GL guest's frames arrive on the X window's own
    surface, and this game also binds an override it never presents on, so the
    blind never lifted. GameNative/gamescope#32: the blind lifts on the first
    commit newer than the override's binding. Only bin/gamescope differs from
    20261104.1.

RP6 verified: title screen at 60 fps under gamescope, blind on at map and off
16 ms later.

Depends on GameNative/mesa#58 and GameNative/gamescope#32.

Bucket-root graphics_driver_download.json updated the same way.

Summary by cubic

Fixes Tomb Raider I-III Remastered (OpenGL) under gamescope, which crashed 3 seconds after mapping its window, then sat black with audio playing. Verified on RP6: title screen at 60 fps, blind on at map and off 16 ms later.

  • extra_libs-20261104.tzst: guest libGL now counts the emulated alpha channel so wglChoosePixelFormatARB finds a 32-bit visual on Xwayland where it previously got no format.
  • gamescope payload 20261104.2: the startup blind now lifts on the first commit newer than the override's binding, so GL frames on the X window's own surface clear it.
  • The legacy flavor now bundles the extra_libs-20261104 archive because it extracts graphics_driver/extra_libs.tzst from the APK rather than the manifest.
