Description Marcelo Bossoni 2023-09-26 20:34:04 UTC 
SUMMARY
Tried to run gamescope git today and it complained about missing functionality in KDE

STEPS TO REPRODUCE
1. Run KDE
2. Try to run gamescope from git branch

OBSERVED RESULT
gamescope is aborted with the following message

Your Wayland compositor does NOT support wp_presentation/presentation-time which is required for VK_KHR_present_wait and VK_KHR_present_id which is needed for Gamescope to function.


EXPECTED RESULT
Gamescope works

Would a backport be considered in 5.27.10 or 5.28.0 ? :)
Just asking; if not no worries.

Tried applying the patch for that commit to 5.27.8 and it wasn't compatible, unfortunately.
I was actually going to ask today when this would be implemented, but it looks like I'm going to have to wait a while longer on Gentoo stable to get it...
Assuming it even gets backported? :/
Plasma 6 is still a baby right now, so it would suck to have to wait that long for this.
