Weird performance drop/crash with multisampling

When I enable multisampling in opengl (Windows) I experiment an extreme performance drop whenever I resize the window over a certain size. It goes from 90fps to 3 fps just by barely exceeding that threshold. Sometimes it’s a crash instead of a performance drop. I can’t debug the crash because it’s a graphic driver crash (“The nvidia opengl driver detected a problem with the display driver and is unable to continue”). I’ve tried to look what’s going on in pstats but I get the same crash whenever I start the app with pstats. This all happens only with multisampling set to 1. Just wondering if anybody has experienced this?

(Yeah, I have updated drivers)

Driver issue. Some driver issues cant be solved.
