Occasionally, whether on the title menu or in game, the screen will freeze.
The game still runs, sounds play, menus click, window can be moved etc.
But no more frames,
Not 0 fps either, (waited forever once, it didn't ever right).
And if I try resizing the window the image just gets cropped off.

If it happens again I'll force crash and drop you latest.log and the report.

EDIT:
I should note that when this happens, it takes several minutes even an hour of run time, to manifest.
Dropping the crash report and latest.log...
