Graphical Crash in Doedre's Cesspool.

I play PoE in Fullscreen Windowed mode. On two consecutive occasions, upon entering Doedres Cesspool in Act 8, about 20-30 seconds after entering, the game changes to windowed mode, changes the resolution to a slightly different custom resolution, then the game disconnects to login.

The second time it happened, I left it in windowed mode, changed the resolution back to my normal one and had no problems.

This hasn't happened anywhere else this league.

Let me know what other information you might need from me and I'll post it.
