While I look for ways to fix these problems, you can try running the game using the built-in graphics adapter. (if available)It is also useful to know your system configuration.
10700k / RX6800 / Win10
Using the iGPU on the 10700k (UHD 630) does solve the issue.
So far, it seems that problems are only seen with AMD RX graphics cards.I will work to resolve this issue. Thanks for the information!
