https://bugs.winehq.org/show_bug.cgi?id=43060 --- Comment #8 from Anthony Jagers <noonetinone(a)gmail.com> --- You are using mesa which means __GL_ExtensionStringVersion won't work. Let's say it again. The reason for the buffer overrun is because the opengl string is too long. You need to have it truncated. I can't help you any further because I don't have COD1 installed. I did ask for advice in reddit for this issue. Try the environment variables per game, then when you start steam or try it when you start your X server. At one point or another it it bound to work. https://www.reddit.com/r/linux_gaming/comments/6hzo2x/weekly_techsupport_thr... -- Do not reply to this email, post in Bugzilla using the above URL to reply.
