Using two NVIDIA GPUs with all monitors ok in the first gpu, one is always black on second gpu. (Although the cursor does move between them and I can see it on the black monitor too - only wayland)

I'm using two GPUs, and while all the monitors are okay on the first GPU, one is always black (the cursor does move ok) on the second GPU (it works fine on Xorg). It's just Wayland's issue.

I'm facing this issue on (https://gitlab.gnome.org/GNOME/mutter/-/issues/3733) Gnome, although it also happens on KDE. I'm using the last 560 drivers.

@amshafer @kbrenneman I finally got some rendering on my monitor's second GPU (also showing on nvtop), debugging/changing some code here https://github.com/gilvbp/egl-wayland. Could you guys help me? Thanks

Sorry for forgetting to update here, we have a reproduction of this issue and are looking into it. I don't have a timeline for a fix yet unfortunately.
