Description (last modified by ming)

When a new render window (either preview or stream) is created and currently another render window is active, sometime both rendering processes got stuck. After manually resizing main window, all rendering processes continue normally.

The problem only occurred on Windows, Mac is unaffected.

(In [4060]) Re #1355: vidgui: new rendering window may cause all rendering processes to stop
Despite this fix, there is still a possibility that the rendering window can occasionally get stuck because SDL_PollEvent() gets stuck. This is most likely because there are two unsynchronized event pollers, Qt and SDL. The problem only happened on Windows with SDL 1.3 r5538, runs fine on Mac.
