Wrong maximize on secondary screen
> My primary monitor is 4k, secondary is 1920x1200. Using 125% scaling.
This is an unsupported configuration on X11, which is known to become even worse and sprout bizarre visual problems like the one you're experiencing when you enable PLASMA_USE_QT_SCALING=1. That's one of the reasons why we haven't enabled it by default, in fact.
You should try the Plasma Wayland session, which handles this setup out of the box. It's really quite stable and usable in Plasma 5.21, and getting better all the time. I'm using it right now, and I'm picky about broken systems. :)

Created attachment 132917 [details] Wrong maximize on primary screen SUMMARY Maximize does not work correctly when PLASMA_USE_QT_SCALING=1 STEPS TO REPRODUCE 1. Set PLASMA_USE_QT_SCALING=1 2. Reboot 3. Start maximizing windows OBSERVED RESULT On the primary monitor, the window does not occupy the whole screen. On the secondary monitor, the window grows bigger than the screen, extending to the primary.
