It has nothing to do with Wayland though, based on the description. Wayland used the base kernel API to manage the display. That is probably broken on your given device.

X11 often gets patched by a proprietary nvidia blob (the nvidia driver), which uses a separate, non-standard, X-specific API.

May be. As i wrote: Intel gpus. All I know is the problem was gone with an X session and nobody at the distro or some boards showed any interest. Not a good way to make sure code works methinks.
