Black Screen In-game

[PLebre]

I also have that black screen with a center red square after starting the launcher.
On my side, I can play the game, but have lots of freezes/stuttening, that didn't had before the patch.

Also download the patch twice, from diferent links, tried the clean install, cleaning the cache, going back to the previous patch, unsyncing with steam cloud, extracting with winrar (not manually)
