Which scaling are you referring to? Is this X11 or wayland? Please include output of env and `xrdb -q` in the broken setup (In reply to David Edmundson from comment #5) > Which scaling are you referring to? Scaling in Plasma settings. I have a UHD display and 225% scaling. When I switch the system from one GPU to another, Plasma shows 225% scaling, but in fact it is 100%. Look at the attached screenshot. > Is this X11 or wayland? X11 > Please include output of env and xrdb -q in the broken setup env https://paste.opensuse.org/37174141 xrdb -q https://paste.opensuse.org/16857491 Temporary solution I created a script ~/.config/plasma-workspace/env/nvdpi.sh and wrote in it export QT_SCREEN_SCALE_FACTORS=$QT_SCREEN_SCALE_FACTORS"eDP-1-1=2.25" eDP-1-1 <- xandr output on NVIDIA 2.25 <- 225% scaling Created attachment 142227 [details]

Thank you for helping us make KDE software even better for everyone!

So I changed the script ~ / .config / plasma-workspace / env / nvdpi.sh QT_SCREEN_SCALE_FACTORS = "2.25; 2.25" This works on two monitors. Scaling problem when switching GPU only with QT applications, maybe there is a way to fix it? After installing the proprietary driver, the font in the Viber application is displayed in small font. In Xorg everything is smooth, but everything slows down. Thanks. После установки проприетарного драйвера, шрифт в приложении Вайбер, отображается мелким шрифтом. В Xorg всё ровно, но всё подтормаживает. Спасибо In Plasma 5.27 GTK applications don't scale when you switch to a second GPU.
