--- Comment #15 from Roberto Sten_Gun benfi@hotmail.it 2010-11-24 09:33:55 CST --- So, let me know: Fast workaround: Disable in game community and override gameoverlayrenderer.dll to disabled in winecfg. This will get source games work back again but disables the in game overlay. Can you confirm that? I'm at university now and I can't open steam. I'll test that on Left 4 dead 1 when I can.
But is curious that raw mouse input related changes in source engine causes a crash when using the renderer.... By the way...Is that bug confirmed in ogher source games? (portal, HL2, CS:S etc)
