(In reply to Józef Kucia from comment #15) Yeah, this is expected. If you want to set MaxVersionGL with Nvidia drivers you should set it to 4.50. Nvidia drivers return the exact version of OpenGL you requested when creating a context (with all extensions advertised).
Interestingly, I tried setting MaxVersionGL to 40005 and the bug still persists with the nvidia binary drivers. In practice I guess it doesn't matter since it works with the compat context, but there may still be a bug somewhere.
