Artifacting in background

64 bit Windows OS
6Gb RAM
1Tb HDD
AMD A8-6500 APU processor with integrated AMD Radeon 6670 HD

Since the latest pre-patch for the space update, I've been getting some severe artifacting on a few different actions, as well as in the background. The permanent background artifacting tends  to show up after 10-15 minutes of play-time and only goes away on game restart. It can make dupes and buildings invisible, which makes playing the game and managing dupes somewhat difficult. This ONLY shows up in ONI. I got a completely different form of artifacting during the last patch as well, but it was really minor and seemed like it could potentially be my PC, but now that that artifacting has just been outright replaced, I'm starting to suspect this is simply a bug.

Things I *have* tried:
Setting integrated GPU to performance to make sure it's using the correct card
Using F4 menu to make it go away (this sometimes works, sometimes does not)
Verifying game cache on Steam
Deleting and redownloading game files
Running game in compatibility mode and as administrator
Turning off all firewalls/antivirus
PC restart

Things I have *not* tried:
Different PC but same game files

I attached a couple screenshots of the permanent stuff, I can't guarantee screenshots of the bubbles that happen on animations, but I'll see what I can do.
