[Interest] How do I get a QMenu to react to text size changes on Window's High DPI displays

[David Garcia]

Hi Elvis,

I did some extra tests and seems that is a bug.

If you start Qt Creator at 200% all is fine. Going back and forth between
100% to 200% works. If you start Qt Creator at 100% then it fails.

I have filled a bug report: https://bugreports.qt.io/browse/QTBUG-72823

Saludos,

David

Just chiming in to say I've noticed this as well and always thought it was a
Qt bug. It was on my personal TODO to look up whether it was reported and if
not, report it. Interesting to hear that Qt Creator behaves correctly (I
hadn't tried it).

I believe (can't quite remember) I've seen similar issues with scroll bars
not adapting fully to runtime changes in the Windows screen scaling options.
