Bug ID: 449681
Summary: Scaling on wayland results in glitches everywhere
Product: kwin
Version: 5.23.90
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED

Screenshot demonstrating the problem
SUMMARY
I use a laptop which max resolution is 1366x768. The elements look too big on
screen for both X11 and Wayland sessions but the Wayland session allows for a
scaling feature, which neatly reduces the size of everything on screen while
still retaining pixel sharpness unlike some X11 workarounds. Thing is, prior to
5.23.90, this scaling was pretty much perfect. After this update, the scaling
does not work on certain elements, such as window decorations. They keep the
exact same size after reducing or increasing the scaling, resulting in visual
glitches in the process as well. Other elements, such as plasmashell, show
visual glitches on the icons. I don't know how far this scaling problem goes
but it seems to be a regression from 5.23.5
STEPS TO REPRODUCE
1. On Wayland session, turn the scaling to 75% or lower, or 125% or higher
OBSERVED RESULT
Screenshot attached to show result
EXPECTED RESULT
All elements on screen to be scaled properly instead of stay the same size as
before and generate visual glitches.
