Using Moonlight to stream(H264) from a Windows 10 PC(960) to a Linux PC(4060) can cause XID 68. This seems to be an issue with newer drivers as I don’t remember this issue existing before 550.
Unrelated but when using the 960, I get lots of encoding artifacts smeared across the screen. That has existed for years but it would be great if it was fixed.
