I’m running three monitors on my setup, one main 144hz 27in. as my primary monitor, one 60hz 24in. as my second monitor, and a 50 inch Sony TV as my third monitor. I’ve been having an issue with KDE scaling the UI elements and applications on my regular monitors to the size of my TV with applications launching with the taskbar covering window headers and even the tabs selector on firefox (I keep my taskbar on the top of the screen, I’ve been working around that particular issue by moving it to the bottom temporarily).
I have tried changed global scaling in display and monitor settings, booted with the TV unplugged, gone through everything I can think of in nvidia settings, reinstalled nvidia drivers and tried open source drivers, disabling KScreen, and even tried an obscure reddit comment’s suggestion of adding “PLASMA_USE_QT_SCALING=1” to my etc/environment file. Still despite this nothing changes with my desktop scaling and it keeps all of my monitors at a scaling as if it was a TV while the resolutions and aspect ratios are the settings native to each monitor.
It is worth mentioning that this issue started when KScreen stopped detecting my primary monitor after login randomly after a PC restart the other day, I fixed the detection issue by deleting the KScreen folder in the /.local directory and rebooting to recreate those files, though the scaling issue stayed after fixing the detection issue.
Does anyone have any idea how to fix this issue or what could be causing it?
