While Plasma supports fractional scaling of Qt apps very well, the fractional scaling does not apply on GTK apps.

GDK_SCALE=2 appname can apply a scale factor 2, but it does not work for fractional scaling.

Is there any way to apply fractional scaling on GTK apps running on KDE Plasma? I am using Plasma 5.24.4 in Kubuntu 22.04.

This does not answer your question, but it may be useful to know for people in the same quandary that, as per the documentation, for now the GNOME/GTK scaling only supports scaling by integer numbers. So, 2 will work, but 1.5 won't.

The global scale factor is now inherited by GTK apps when it’s an integer (Peter Eszlari, KDE Plasma 5.15.0)
