A few weeks ago, another moderator moved a help question out of General Discussion:
We ask that you do not use General Discussion for help, advice, or troubleshooting. I have moved this to #gd-commsupport:world, as this is a scenery-related issue. It would also be okay to post this in #gd-commsupport:tech-talk as a graphics issue, but I know you mentioned that you ruled out your graphics card.
