The issue you are seeing is a different bug and I'm not sure whether it is a Wine or GLX bug. At this point the glxinfo output looks correct and it should never be able to call glXCreatePbuffer but for some reason it is called. As Henri mentioned create a +wgl log, so run: WINEDEBUG=+wgl wine tibia.exe &> log and post that log.
The GLX message is just a warning, but the screen being offset from the bottom of the window does look like the existing screenshot in this bug. That GLX warning is still something that should be fixed, but it's not something for this bug.
