Bug ID: 433094
Summary: No way to disable tearing prevention
Product: kwin
Version: 5.21.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: multi-screen
Assignee: kwin-bugs-n...@kde.org
Reporter: fynnb...@gmail.com
Target Milestone: ---
SUMMARY
The new kwin version (5.21.0) is unusable for me, I'm running a dual monitor
setup, one monitor with 144hz the other 60hz.
In the old kwin version there was an option to disable tearing prevention which
is now missing.
Without disabling tearing prevention moving windows feels very sluggish and
seems like it's capped to 60hz.
I have tried numerous workarounds (such as adding "MaxFPS=144" to the kwinrc,
setting the environment variable "__GL_SYNC_DISPLAY_DEVICE" to my 144hz
monitor, playing around with NVIDIA Settings (also tried
Force(Full)CompositionPipeline, trying out all of the new vsync options,
basically everything there is) but nothing helps.
Would it be possible to bring back an option to disable tearing prevention?
STEPS TO REPRODUCE
1. Update to new kwin version
OBSERVED RESULT
No way to disable tearing prevention.
Moving windows and other compositor related things seems to be capped to 60FPS.
EXPECTED RESULT
An option to disable tearing prevention like on the old version
