History of Application UI scaling

I think that my next target has to be Qt6 and the control panel for that is currently saying it is not loaded properly so a good starting point. Environmental settings need adding which have not been handled by the various installers?

I think that my next target has to be Qt6 and the control panel for that is currently saying it is not loaded properly so a good starting point. Environmental settings need adding which have not been handled by the various installers? QT_QPA_PLATFORMTHEME = qt6ct seems to be what is missing.

'QT_QPA_PLATFORM=xcb' is not necessary for LibreOffice since it is already reporting that it is using xcb so perhaps trying "SAL_USE_VCLPLUGIN=gtk4" to to use the alternate gtk toolkit. However that seems to be more problematic on high resolution monitors. PDF Arranger is using gtk3 and it's top windows bar has irritatingly small icons so the right click menu gets used instead.
