SUMMARY
Proper support for Gamescope under Wayland requires wp_presentation/presentation-time, which is now supported for Plasma 6...
https://bugs.kde.org/show_bug.cgi?id=474918

But Plasma 6 is a ways off and is still in alpha; this should preferably be something supported for Plasma versions that are already in production. (Plasma 5)
I'd like to request that this please be backported somehow.


STEPS TO REPRODUCE
1. Run a KDE Wayland session
2. Install gamescope
3. Run `gamescope -w 1920 -h 1080 -W (whatever resolution) -H (whatever resolution) -S stretch  --nested-refresh=60 --expose-wayland -- (any GUI program here, but it's meant for games)`

OBSERVED RESULT
"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
For Plasma 5 to support this, because Plasma 6 is in alpha.

SOFTWARE/OS VERSIONS
Linux: Gentoo
KDE Plasma Version: 5.27.9
KDE Frameworks Version: 5.112.0
Qt Version: 5.15.11

You do realize that closing this as a duplicate of an also closed report won't get it seen by people actually looking for problems to fix, right?

Hi, given that a backport was already asked for in 474918, I thought that it would be better to consolidate the different reports. Also, given that plasma 5 has been on feature freeze since January 2023, and is currently in EOL with no future releases scheduled [0], I think new features won't be eligible for backport, unfortunately. On the other hand, the beta 2 of plasma 6 has just been released, and you might be interested in trying that out.

Thanks for understanding!
