Is this happening to other people? Nothing I've done should cause silliness like this!
Have you tried changing zoom levels, or switching to full screen and back? It seems like it's using a resolution not divisible by 640/360, which Windowed frankly shouldn't be able to do...
About the patch, I've just been "fixing" some elusive bugs where I'm not certain about the causes. I'm silently patching because I don't feel the patch notes would be very interesting with a bunch of "With some luck, maybe it won't crash in super weird non-reproducible circumstances when connecting to multiplayer sessions where there are a lot of pets" etc
