I was trying to play Oblivion on wine-1.1.35 (Gentoo) and I get an error: wine: Unhandled page fault on read access to 0x00000000 at address 0x68fda1 (thread 0009), starting debugger... fixme:dinput:SysMouseAImpl_Acquire Clipping cursor to (0,0)-(1440,900) This looks like it is related to the fact that I'm using dual screen on nvidia-settings, because I'm able to play with no issues when only one screen is enabled.
