For clarity, here's what I posted in the other topic:
Hi guys, just wanted to chime in here. First off, I'm sorry for the trouble with the video corruption. Unfortunately this particular issue is some kind of bug or incompatibility between .NET Core and certain video drivers. Out of curiosity, what video cards do you have?
This one is a tough one because it's either a Microsoft or a driver bug, and so there's very little we can do to try and fix the issue. We use Microsoft's WPF to render things in LaunchBox and Big Box, so unfortunately that means that if WPF has a bug, LaunchBox and Big Box will too. If I had to guess, though, this probably comes down to a bug with certain video drivers. I would first try updating your video drivers to the latest version available, and then making sure that you're 100% up to date on Windows updates. I would even try updating to the Windows 10 May 2020 Update if you haven't already:

If worse comes to worse and there isn't a fix available for your system yet, I would recommend staying on the 11.2 version until Microsoft and/or your video card manufacturer fixes the issue. Here's a link to download 11.2:
