SUMMARY
When using a 150% scale factor, some texts and controls seem to render incorrectly: some characters look stretched or compressed, and straight borders of control may look distorted. It happens a lot less frequently with 175% and does not seem to occur at all with 200%.

This is not only seen in Plasma Shell, it also occurs in e.g. KRunner, Spectacle, and System Settings. My guess is that it only happens with QtQuick interfaces, not QtWidget ones, such as KWrite. It also doesn't happen in Plasma 5.

STEPS TO REPRODUCE
Change the scale factor to 150% and navigate around.

OBSERVED RESULT
Some texts look strange. Sometimes the hovering state of an item can also affect the text inside.

Is it a duplicate? I don't see this issue in Plasma 5 though.
Comment 6 Nate Graham 2023-10-20 15:33:11 UTC 
It was also a problem in Plasma 5. It may have gotten worse in 6 due to Qt 6 changes, but in any event the solution would be the same.
