Bug ID: 445940
Summary: Random rectangular regions of the window are filled
with blinking garbage
Product: kate
Version: 21.08.2
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal

SUMMARY
STEPS TO REPRODUCE
1. use Kate
OBSERVED RESULT
At random times, some random rectangular portions of Kate's window (which may
randomly cover both the text and/or the UI), usually not very big (like in the
order of a few dozens pixels in width and height), are filled with garbage,
usually some horizontal or vertical gradient from white to gray, resembling a
very small piece of a window's border's shadow insanely up-scaled (I'm not
saying that's what it is, I'm just describing what it looks like). And it
"blinks", alternating between two or few different "frames".
These won't go away by passing the mouse cursor over them, but they do go away
by moving Kate's window, switching back and forth between tabs, or giving focus
to another application and then back to Kate.
