Is this a known exposure bug in Windows

[lni]

I have a workspace, where internal MDI windows display various graphical items. When I maximize the main window, the MDI window exposes but the MDI windows that got exposed are not redrawn.

As shown in the attached screen dump, the bottom portion is missing...

This only occurs in Windows. In Linux everything is fine. Is this a known issue? This happens all time... I have to move the MDI window, or iconize the main window and re-open it to get it right.


Thanks

Are you able to reproduce it with a minimal compilable example?

I have been using QWorkspace all the time until I checked the doc a while ago and realize it is deprecated and obsolete!

So I switch to QMdiArea and QMdiSubWindow and it appears to work alright so far.

Too many deprecation occurring in Qt!

I think that I saw much more in Java when I was making my school projects...
