Weird view drawing behavior and fix

I was about to post and ask if anyone has seen this weird view drawing behavior before, but while grabbing screenshots and system info, I stumbled across a fix. So this is an FYI post.

I get these weird drawing artifacts occasionally when opening a file if I have Parallels running at the same time, but this morning it happened without Parallels running. After grabbing a screenshot and dumping my system info, I thought to check the preferences for video settings. Turns out, if I change the anti-aliasing setting in the OpenGL pane, it refreshes something and fixes the issue. I was at 4x, I changed to 2x, then changed back to 4x and the problem didn’t return, so just making the change refreshed whatever was causing the problem. Definitely a bug, but not a critical one and there’s an easy fix when it happens.
