UPDATE 9-2-20 Has your Sims 3 game been affected by the recent pixilation issues?

I also tried all of the fixes @Archivist posted. But, I found a site where I could test to see if it was a problem within TS3 for me or outside of TS3. The gradients looked perfect in the test, so I assume this is just a TS3 issue. At least, for me. Color banding has always been a mild problem in TS3, but the color banding recently is noticeably worse.
