I've had a crash issue (once) when going from Bordered Window mode to Full Screen mode in-game, the program crashed and kicked me out.

I've also had a BSOD (twice) from playing in Full Screen mode.

I've had no problems whatsoever (other than FPS drop) while playing in Bordered Window mode.

These things tell me that there's a problem with the full screen mode, but player results here who still get it in Window mode leave me clueless
