I was starting to think I was the only one having this issue. I installed the latest update to sl viewer this past week and when I signed back in it was immediately obvious that something was wrong with the graphics. The texture glitches were so bad I had to stop using sl because I was becoming ill. Judging from this thread it appears there is no immediate cure. It seems like every time I update the sl viewer my experience gets worse. Is this really progress LL?
