SUMMARY
STEPS TO REPRODUCE
1. Install KWin 6.1.90 and login to a Wayland session
2. Start RetroArch with the Vulkan video driver (make sure it's a native
install and not the flatpak, as the issue does not occur in the flatpak)
3. Start any game with a black screen
OBSERVED RESULT
Black is RGB hex code 060606 instead of 000000
EXPECTED RESULT
Black should be 000000.
SOFTWARE/OS VERSIONS
Windows:
macOS:
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.2.1
KDE Frameworks Version: 6.7.0
Qt Version: 6.8.0
ADDITIONAL INFORMATION
When using KWin 6.1.5, it works fine, with black appearing as RGB hex code
000000. It also works fine in KWin's X11 session (version 6.2.1.1). It also
works fine in the latest weston, and using RetroArch's OpenGL (both glcore and
gl) drivers in the Wayland session.
Other Vulkan applications do not show this issue (tested with PCSX2 and rpcs3)
I have RetroArch installed using the `retroarch-git` AUR package, and I have
tried pinning the commit to the latest stable version with the same results, so
it is not a RetroArch issue as far as I'm aware.
