alexey.lysiuk 83c6798651 Fixed a very slim chance that window will be white and empty after startup
There are a few quite specific steps to reproduce this issue:
* 640x480 video resolution
* -iwad ... -warp ... command line parameters
* OS X 10.4 or 10.5 PowerPC, maybe performance related
When all these requirements are met, content view doesn't show up sometimes
The simplest solution for this issue is to set initial window size to non-existent video resolution
