Virtual desktop broken in multi-monitor setup (all games) #1684
Description
I'm on a multi-monitor setup, running the latest Nvidia drivers on my GTX 1070. Running any game in a virtual desktop results in it rendering as just black.
If I put the virtual desktop window on my left-most display however, it runs perfectly fine, and once I drag it back to a monitor that isn't left-most in the X-screen, it goes back to just rendering as black. I've seen a few other users on reddit with the same issue, currently its stopping me from playing games that rely on emulating a virtual desktop to have functional mouse input (Fallout 4, etc..).
Edit; Some additional details:
3 monitors arranged left-to-right
I7-7700k
GTX 1070 (Very latest proprietary drivers)
Lubuntu 17.10
Linux 4.13.0-46-lowlatency
issue is present on every proton version up to the latest beta.
