Anybody get these? It happens if I mess around in the menus too much. Specifically, if I go in to change a board type or com port. Not specific to RA. I got them with stock Arduino as well.
I've searched for it before, but this time I came up with a post that actually helped. I used a program called Driver Fusion to wipe all the graphics drivers (old and current) and then re-installed the latest drivers. I'd re-installed before, but never fixed it. I'm guessing there were some old drivers hanging around screwing things up.
