Bug ID: 475549
Summary: Intermittent Flickering/Disappearance of Browser and
Task-bar panels during Plasma-Wayland sessions.
Classification: Plasma
Product: kwin
Version: 5.27.8
Platform: Archlinux

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See

STEPS TO REPRODUCE
1. Install Archlinux/NVIDIA Proprietary Driver/KDE Plasma/SDDM/Wayland per
Archlinx Wiki
2. Select Plasma (Wayland) on SDDM Greeter, Enter Credentials, Select Login
3. Open Konsole terminal instance, Open Firefox browser instance
OBSERVED RESULT
Occasional flickering panel/window disappearance, primarily of the browser
panel, but sometimes of the task-bar panel, during which the desktop image
behind the browser panel may be seen for periods ranging from a fraction of a
second to 15 seconds. Other artifacts, such as stuttering during scrolling of
text windows and slowed response of the mouse along with a paintbrush effect
(see attached video) are also present. Occasionally, the trim of the browser
panel (menu-bar, url-bar, & side panels) flicker/disappear while the central
browser window is unaffected. None of these artifacts have been observed to
affect the Konsole terminal panel so far.
The video attached is far from representative. It is difficult to record
because none of the problems have ever been observed when screen recording was
occurring (using OBS Studio). The problems only occur when the screen recorder
is not running. As a result, I am only able to record evidence of the problem
with my phone, which is less than ideal. Since the occurrences are frequent but
relatively brief, it has been difficult to get a good video of the problems.
EXPECTED RESULT
No visual artifacts. Smooth mouse response and text scrolling.
