Bug#1104156: gamescope: crashes under Wayland Vulkan renderer due to DRM_FORMAT_INVALID

[Alex Dowson]

Package: gamescope
Version: 3.16.1-1
Severity: important

Dear Maintainer,

Gamescope 3.16.1-1 currently fails to run under Wayland compositors using
Vulkan (e.g., sway with WLR_RENDERER=vulkan). It immediately aborts with:

gamescope: ../src/Backends/WaylandBackend.cpp:1594: virtual void
gamescope::CWaylandBackend::GetPreferredOutputFormat(uint32_t*, uint32_t*)
const: Assertion `u8BitFormat != DRM_FORMAT_INVALID' failed.
Aborted

An upstream pull request has been submitted to fix this:
https://github.com/ValveSoftware/gamescope/pull/1826

Related upstream issue:
https://github.com/ValveSoftware/gamescope/issues/1604

Until the patch is merged and packaged, gamescope is unusable on Vulkan-based
Wayland compositors.

Thanks for maintaining the package.
