[CRASH] Client crashes computer immediately after login
After getting past the login screen, the main client window contains a bunch of empty black boxes. Seconds later, the client freezes and shortly after that the entire computer freezes and becomes unresponsive requiring a hard shutdown. Tried four times in a row with same result. Usual fixes (Messing with compatibility issues, running as admin) were not successful on subsequent attempts to login.
