If I open my game normally, text doesn't flash, and I get MaV always as random spot of game.
When I open the game with "use the GPU" (I don't know, what it says on english PC) and I select NVIDIA, the text start flashing, but game works otherwise normally, and it doesn't crash.
It has happened every version I tested :(

Flashing text is a FastText bug with certain GPUs. Unfortunately, there is no known fix for this issue without removing FastText entirely.

As for Memory Access Violations, it's probably the DrawPortal in 860's room. It uses a special effect that FastExt adds, which doesn't work on certain systems. The only known way to fix this may noticeably reduce the visual quality of the DrawPortal.
