No freezing scaling at 175% or below, can move GUI to different screen. freezing at 200% or above, crash when moving GUI to different screen. happens both with external monitor and laptop screen only, both start freezing at 200%. This is with ASUS Zenbook Duo with Core Ultra 9 iGPU and 3k screen, it has two screens but with one screen active.
When tested 1.14 and initially 1.15, used another Zenbook Due with 1080p screen, max scaling allowed 175%, explains why no freezing then.
Tried on another laptop (1.15.1) with 4K screen, a thinkpad with RTX 1650 card, no freezing at all at any scaling....
only have two laptops with 4k screen, can't set >175% unless >3k screen.
