SUMMARY I've seen this behavior only in Prusa Slicer so far, but before I upgrade to 5.27 today (and also to kf 5.103), it now doesn't scale. If I run it with GDK_SCALE set, it starts normally as I usually see it. It doesn't matter if I set "GDK_SCALE" or "GDK_SCALE=1", result is the same. I didn't use any env variables before so I think there could be some regression. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.0 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.12-zen1-1-zen (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon RX Vega M GL Graphics ADDITIONAL INFORMATION Prusa Slicer is wxgtk app, I have wxgtk 3.2 and it uses gtk3 backend.
Created attachment 156313 [details] no GDK_SCALE
Created attachment 156314 [details] GDK_SCALE=
Just as I filed this issue, I opened discord and it has same behaviour. Interface is tiny and if I launch discord with GDK_SCALE= discord, it starts having normal scale. So I suspect it isn't wxgtk nor prusa-slicer issue.

Just to clarify "doesn't scale" == looks really small on your high res screen?
