Bug ID: 491429
Summary: Kwin forces VRR despite it is off, easy repro step
included
Classification: Plasma
Product: kwin
Version: 6.1.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: yurneroli...@yandex.com
Target Milestone: ---
SUMMARY
Kwin has completely borked VRR handling as of now. Set VRR to Auto ( means no
VRR at desktop etc ) , play a game that switches between some locked fps
between main menu/gameplay etc, return to desktop afterwards. Open up your
monitors refresh rate ( not FPS ) counter, see how it jumps between lowest hz
of VRR range and highest. ( Respectively 48 and 165 for me ).
If easier repro step wanted ( no game ) , open MPV with wayland context and
Vulkan. Notice how VRR is enabled and jumpy. Afterwards set a window rule for
MPV to DISABLE vrr open MPV again. Notice how vrr is not disabled at all.
Return to desktop, notice how desktop acts like VRR is forced. Disable VRR from
KDE settings, notice how it doesnt change anything.
Restarting the system fixes the issue, until you repro again.
STEPS TO REPRODUCE
1. It was a bit long so i couldnt breakdown it to three steps. Written above.
OBSERVED RESULT
VRR itself ignoring any setting and window rules with steps above.
EXPECTED RESULT
To not do that.

KDE Plasma Version: 6.1.3
