Bug ID: 435361
Summary: Graphical glitches (flashing) under wayland in kate
Product: kwin
Version: 5.21.3
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: xnw...@yandex.com
Target Milestone: ---
Created attachment 137332

A recording of the symptom.
SUMMARY
This is likely related to kwin but kate is the most common one that I noticed,
whenever I press Ctrl+S, the line number column has a big chance of producing a
flash. Fast flashing images really makes me uncomfortable so this makes kate
very difficult use for me.
STEPS TO REPRODUCE
1. Launch kate in a plasma wayland session
2. Press Ctrl+S
3. If you don't see it, press Ctrl+S again and again (but do not hold it down)
OBSERVED RESULT
The line number column sometimes flashes.
EXPECTED RESULT
There should be no graphical glitches.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 34, kernel 5.11.11
(available in About System)
KDE Plasma Version: 5.21.3
KDE Frameworks Version: 5.80.0
Qt Version: 5.5.2
ADDITIONAL INFORMATION
Changing compositor rendering backends does not help with this situation, and
this does not happen in x11 sessions.
I am using an RX550 with the amdgpu driver.
