Bug ID: 468304
Summary: KWin lock frequency on 60 Hz
Classification: Plasma
Product: kwin
Version: 5.27.4
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: egor.kuznetsov...@gmail.com
Target Milestone: ---
SUMMARY
I noticed that if I enable the AMD Freesync option in the monitor settings, and
then set the screen refresh rate in the monitor settings to be different from
165 Hz and possibly higher, the monitor and KDE continue to run at 60 Hz.
However, this behavior does not depend on the set option for Adaptive sync in
Display Configuration in System Settings (if I set Never, for example, Hz lock
still exists)
STEPS TO REPRODUCE
1. Turn on AdaptiveSync (maybe it will be called FreeSync in other model of
displays) in display settings
2. Choose any refresh rate up to 165 Hz
3. Accept new refresh rate
OBSERVED RESULT
Display says that refresh rate is 60 Hz and I visually noticed that desktop
compositing still runs at 60 FPS
EXPECTED RESULT
Display must operate at the frequency specified in the display settings
