Hmm, that's not the behavior I see at all. For me, `factor` appears to be 1 with not running a HiDPi scale factor, so I get an actual size that's essentially equal to the number it's multiplied by. (e.g. `return QSize(1024*factor, 700*factor)` yields window content that's actually 1024x700 ). If I run with `QT_SCALE_FACTOR=1.3 systemsettings5`, everything is scaled perfectly. Do you have some wonky DPI settings on your test box or something?
