update 20200130 "stripes" the preview in horizontal lines as a result of which it is not clear. The other parts of the menus seem to be fine. I restored the original installation and the problem was resolved. I installed the latest update again and the same problem was repeated. Any suggestions?
Can you try updating the video driver? That or go back to the original. I don't recall the 'update' was critical. You'll probably be fine without the update.
