Strange plug-in window sizing

With the last few plug-ins I’ve installed, Cantabile 4203 is giving me too small a window to view the content - and no re-sizing controls. The latest example today is Ozone 11.

I switched off the high DPI option, which seems to cure the problem.

Am I compromising anything by turning off that option?

Odd. Only me seeing this, then? I’m beginning to suspect my video drivers, if this is the case - NVidia RTX3050.
