When II use vats or try to build things in the workshop, the whole screen just goes green pixels or yellow pixels or red pixels or white pixels. I am not sure how to upload a screenshot in this forum, but I will later. Please help

What GPU do you have?

If you have an Nvidia, update your drivers. !!!

Thank you very much! The issue seems to be resolved. I updated my drivers and that seems to have fixed the problem. Thanks again for your reply!
