Nivida Prime Render Offload - Blank Second Screen

[dcrdev]

Ever since proton-5.13-4 games start up completely black on my second monitor and they freeze. If I start the game on my primary monitor - things are fine, but as soon as I drag it across to the external - it goes black; but unlike starting it up on the second monitor - the game continues to run when black.

This seems to be an issue as of proton-5.13-4, if I downgrade proton to that - everything is fine.

System Info:

• Fedora 33 / 5.10.15-200.fc33.x86_64
• 2080 Super Max-Q / 460.39
• i7-10875H

hmm, that is interesting regression

i dont have these issues shifting between monitors on any versions of proton

So I was trying to take a screenshot showing it working on one monitor and then going black on the other.

Interestingly when I printscreen - it momentarily comes back and so the screenshot looks like it's working fine.

It's a very interesting problem; not one I have any inkling of how to troubleshoot/debug. Like I said downgrading works fine - which is fine for the majority of the games I own; but no good for newer titles like Cyberpunk.
