kolourpaint glitches
SUMMARY
I'm getting various graphics glitches with 1.25x scaling (or any fractional
scaling factor inbetween 100-200%)
One symptom is in kolourpaint if i use the selection tool to select something
and then shrink back the rectangle(see screenshot) . If i open kolourpaint in
xwayland mode with "Legacy X11 applications = scaled by the system" the bug is
there. But with "apply scaling themselves" bug is gone.
This also happens with Pinta but curiously does not happen with Gimp or
Drawing.
The other one is with coloured text characters in konsole. Originally reported
here but with no resolution and i assume they're related:
https://bugs.kde.org/show_bug.cgi?id=491562 Similar x11 behavior as with
kolourpaint.
Possibly related: https://bugs.kde.org/show_bug.cgi?id=466373
STEPS TO REPRODUCE
1. set fractional scaling to 1.25
2. open kolourpaint
3. drag a selection with selection tool and shrink it
OBSERVED RESULT
visual artifacts

no visual artifacts
