Qt Creator not painting it's main window interior

[rudi]

When starting Qt Creator (DIVE mode, SNAP) the main window interior is not painted. The window has to be moved or resized manually in order to be drawn. This is most likely a regression of the recent changes in the drawing code.

A similar issue can be observed with Qt Designer's "New Form" startup wizard.

Hmm, indeed. Actually, any application shows this problem in DIVE mode, even the textedit demo. Quick testing shows that r1019 is guilty. Strange...

[Dmitry A. Kuminov]

No, I cannot actually reproduce it with the current SVN and SNAP, I had some old build. Are you sure you did a complete rebuild?

I can reproduce it with Panorama though (only FB/FBSWM, BLIT mode doesn't show any problems), but Panorama is unable to correctly do Dive anyway, so it cannot be fully trusted here. We need somebody else with the real SNAP hardware to try this too.

Hmm, really strange. The designer problem only shows up here if I reset QT_PM_DIVE. Setting it to either of FB/FBSWM/BLIT explicitly makes it work. It's strange because when QT_PM_DIVE is not set, it should behave exactly as if you do QT_PM_DIVE=FBSWM (on SNAP).

[Dmitry A. Kuminov]

It has something to do with timings as the problem doesn't always happen. Most of the time it works well with QT_PM_DIVE reset.

Fixed in r1076. The variable initialization was missing which could incorrectly delay paint events in DIVE mode. That was a regression of the work I did for #203 indeed.

Thanks for reporting.
