When fullscreen @ 1024x600 switches to windowed mode and back on navigation

STR:

1. Make application fullscreen (in 1280x600 resolution it does it automatically)
2. Navigate through available items in the control center

Expected results:
No resize occurs as the window is already fullscreen

Actual results:
Every time another module is opened or user is navigating to previous view, the window switches to windowed mode, draws the view and switches to fullscreen again.
