Bug ID: 455763
Summary: Plasma 5.25: Present Windows uses too low frame rates
Product: kwin
Version: 5.25.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-present-windows
Assignee: kwin-bugs-n...@kde.org
Reporter: m...@elbmurf.de
Target Milestone: ---
I have a 144 Hz monitor and on a Plasma 5.25 session, the new Present Windows
effect does look like it uses only like 60 fps. This is a bug.
There is of course the FPS effect (which is correctly showing 144/143 Hz) but I
don't know about its meaning for other effects.
This effect feels wrong at this monitor Hz rate, never had this visual
observation with the old implementation, which was rendered super smooth.
AMDGPU driver in use with a Radeon 5700 XT.
STEPS TO REPRODUCE
1. Get a 144 Hz monitor
2. Compare the old Present Windows with the new
3. Cry
EXPECTED RESULT
It should feel smoother. There is clearly something wrong with its frame rate.
It isn’t just the faster speed (https://bugs.kde.org/show_bug.cgi?id=455521),
but also the frame rate feels limited.
