Ohh, weird, since I only experience that on Qt stuff, meaning I see no issues on GTK stuff, but I don't use a GTK DE neither compositor/WM, :(...  Well, I got as well as the LXQt upgrade, Xorg and KWin upgrades:

xorg-server-common (1.20.13-3 -> 21.1.1-2)
xorg-server (1.20.13-3 -> 21.1.1-2)

So perhaps a Xorg issue instead of a LXQt/KWin one?

I have no clue how to force no scaling factor, actually I've set QT_AUTO_SCREEN_SCALE_FACTOR to 0, with no effect.  Before this mess, I never had to touch any scaling stuff for Qt, I've only set GDK_DPI_SCALE=1.5 since GTK3 showed up I believe, but nothing else...

The LXQt monitor settings don't help for anything other than changing resolutions...

Would you thing the Xorg upgrade is the culprit one?  I don't use xfre86 GPU driver, instead I use the mode setting:
