The major change in this version is that in order to use wayland with nvidia-drivers, nvidia-drm.modeset=1 needs to be set -- so USE=wayland does this.
I did fear that it may cause issues for some more exotic setups though thus the postinst elog message to warn about this change when enabling wayland.
To confirm, try to #comment out this line in /etc/modprobe.d/nvidia.conf:
options nvidia-drm modeset=1
As far as I'm aware, this option is also needed for PRIME offloading, but reverse PRIME may be a different deal. Like SLI, I may need to adjust the informational message to warn about reverse PRIME. Unsure if I want to disable this by default given it'll be impossible for wayland to work out of the box.
Unfortunately I don't have the right hardware to test this myself.

Oh!
I forgot about this, I believe gdm will default to wayland if this is set... are you sure you're starting a Xorg session?

Commenting the option: "options nvidia-drm modeset=1" in /etc/modprobe.d/nvidia.conf resolves the issue in my case. I think it's wise to update the postinst elog message and include reverse prime in cases where external displays are hardwired to the NVIDIA GPU (which is the case in most mobile workstations. (The Lenovo ThinkPad P series and higher end Dell Precision series laptops etc.).
