QDockWidget Performance
Message 1 in thread
I have been experiencing performance issues with the QDockWidget on
the Windows platform with QT Jambi TP3. At first, I thought the issue
may have had something to do with my code; however, I am also
experiencing the problem with the "QT Image Viewer" demo.
Everything works as it should while the QDockWidget is docked;
however, whenever I undock the widget so that it is "floating", the
GUI of the entire OS (Start Menu, other applications, etc) drastically
bogs down.
Has anyone else experienced this? Is there a known work-around?

Hi, Brant.
I cannot seem to reproduce this problem. I'm running the ImageViewer
demo and I undock the "Image Effects" widget, but this does not seem to
make any difference to the responsiveness of the UI nor of Windows. Is
there something else I can try to reproduce it? On which particular
version of Windows are you running it?
