See screenshot.

I am scaling my screen 175%. When I do, it seems like the windows themselves adjust neatly; but the taskbar and menu fails and reverts to what looks like 100% scaling, making the next practically unreadable.

Any ideas?

Thanks,
Stephan

What are your font settings, any forced settings like DPI or anti-aliasing excludes?
Please also always specify your exact Plasma version when asking questions...

Noto Sans 10pt for everything except Fixed Width which is Noto Mono 10 pt.

It seems like the system automatically "forced" font DPI of 144 (I didn't set that).

I should add that when I set the resolution to 150% (just a tad to small for me), it seems to work - the windows and taskbar look to be at the same size.

You know I just tried it again and this time, it seemed to take.

Not sure what would have caused this. But I guess for now this is resolved. Thanks!
