After updating 4.20 from the preview build to the release build, this happened:

Whenever I start my game in VR a weird pattern is drawn over all game graphics. Even thumbnails are affected! To make it disappear I have to restart the editor.
The pattern looks a lot like the lens distortion UE applied to VR games.
The preview builds for 4.20 worked just fine, but I can’t get VR rendering to work since the official release.
I can get the pattern to disappear if I take a HighResScreenshot while not in VR. Upon starting the VR mode the pattern reappears though.
Today I discovered that this only happens when I use DirectX. Vulkan and OpenGL have their own problems though, so I can’t really use them. Past version of UE still work - right now I’m using 4.19. I’ve not found a way to redownload the preview builds.
Here are the things I’ve tried:
- Reinstalling UE 4.20
- Creating a brand new project
- Updating my graphics card driver (I’m using an AMD R9 390)
- Deleting my derived data cache (Which I hope I did correctly)
- Creating a topic on Answerhub (heh)
Has anyone else experienced a similar issue? If there’s some clean way to reinstall UE, or if anyone has a list of things for me to try, then I’ll gladly do it.
I am completely open to all suggestions. All answers are appreciated!
