Symptoms

When launching Cyberpunk 2077 in fullscreen in a multi-monitor setup, it picks the left-most monitor.

My setup from left to right:
Samsung Monitor, ASUS 4K Gaming Monitor, Dell FHD Monitor

It displays it on the Samsung Monitor when it should display on the ASUS 4K Gaming Monitor. This does not happen on previous versions of Proton.

Reproduction

1. Have a multi-monitor setup (3 monitors) and use the middle monitor for gaming
2. Launch Cyberpunk with latest bleeding-edge Proton Experimental
3. Note that when Cyberpunk is launched in fullscreen, it displays it on the left-most monitor when it should pick the middle one. (there is no way to make it display on the middle one.)
4. See screenshot for details.
