      Description

      Hi guys:
      I found an issue with wordwrap QLabel on hidpi on two monitors with different scale factors.

      I have two monitors as follows:
      1. primary monitor placed at right (3840x2160 with scale factor 150%) primary.png
      2. secondary monitor placed at left (2560x1440 with scale factor 100%) secondary.png

      I create a fixed size QWidget, and a wordwrap QLabel, then put QLabel into layout of the QWidget, when I move the QWidget from a monitor to another, the QWidget is not under my mouse cursor so it's hard to move the QWidget from one monitor to another. See attachments mytest.mp4.

      Here is a short example to reproduce the bug: qtbug90460.zip

      I also found that the "About Qt Creator" dialog in qtcreator qtcreator.png have the same issue too, see qtcreator-test.mp4.

      My win10 version is 20H2 (19042.746) winver.png.
