(mind the scales)

I have konsoles on this DP-7 monitor.

STEPS TO REPRODUCE
1. switch from one desktop to another
2. maybe vertical maximization and restore to original size is needed before, I don't know for sure

OBSERVED RESULT
Sometimes, one of the konsoles is misrendered. See the attachment. It looks like scaled down by 1.2 -- from 1093 px (the window) to 910 (the rendered content).

EXPECTED RESULT
Proper rendering. Is this konsole's fault? Or is it perhaps some plasma component?

Thinking about it, this is likely related/needed:
When monitors go to dpms off (after inactivity), it takes so long for the DP-7 output to come up, so that plasma "forgets" the output temporarily and moves all windows to eDP. After a second or two, all is moved back to place on DP-7. And this likely causes the problem -- the window is then distorted.
Comment 2 Jiri Slaby 2024-03-22 07:06:41 UTC 
Still happens with konsole-24.02.0-1.1.x86_64.
