Bug ID: 485472
Summary: At a scale other than 100% I see screen glitches at
bottom edge of the screen
Classification: Plasma
Product: kwin
Version: 6.0.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

take a look at the bottom of the screen
SUMMARY
I have a 16" laptop with Plasma. With 100% scale due to the big screen
resolution, everything is too small to read. Even Plasma itself set scale to
150% by default. In this case I see either colored glitches in the form of
dashes at the bottom edge (always) or sometimes it's just a white line at the
bottom of the screen (rarely). Sometimes the white line at the right edge of
the screen (very rarely).
It looks like hardware screen issue. Well it could be. But when I set scale to
100% in KDE there is no issues at all.
When I try Fedora with gnome live usb I don't see glitches even with scale up.
When I installed Windows for update UEFI reason I also didn't see glitches.
Unfortunately, I sold out my old laptop but I'm recalling kind similar behavior
there but less noticeable (can't prove again)
STEPS TO REPRODUCE
1. Go to Settings --> Display configuration
2. Set the scale up to 150%
3. Open in full screen size mode image or video player or similar. It's better
to observe on the black background
OBSERVED RESULT
On the bottom and sometimes on the right side of the screen I see just a few
pixels width artifacts (glitches)
EXPECTED RESULT
Without glitches?
