I tested the new fixes for the KF5 Wayland user interface on highdpi screens. It seems to be properly scaled only for one of the two screens. If the second screen has a different scaling factor, that scaling factor is never used and there does not seem to be a factor change when the LO window is moved from one screen to the other.
Created attachment 178079 [details] UI properly scaled with 2x scaling on the highdpi screen.
Created attachment 178080 [details] UI with 2x scaling on another screen that has 1x screen scaling.
More info about the setup: OS: Manjaro Linux Environment: KF5 on Wayland Hardware: Intel HD with 4K laptop screen and 1080p external screen KDE Plasma: 5.23.5 Qt: 5.15.2
I'm also experiencing this, with LibreOffice version 7.4.5.1 Operating System: Manjaro Linux KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.14-1-MANJARO (64-bit) Graphics Platform: Wayland Graphics Processor: Mesa Intel® Graphics With a 1920x1080 monitor set as Primary within KDE, and a 2880x1800 laptop screen; that Primary monitor is set at 100% scale and the laptop screen is at 200%. Scaling is correct for the laptop screen but the UI is huge on the Primary screen.

To add; I'm noticing this is sometimes the other way around, so that the Primary display scaling is fine but the UI is very small when I move the window to the laptop monitor. It looks like LibreOffice just can't handle having different scaling factors per window.
