Now this is where it gets weird. Since I have Ubuntu MATE, I installed the ubuntu-desktop package to get the default GNOME environment. I kept my display manager as LightDM in case that's relevant.

Then I rebooted and tested all 3 desktop modes with default kernel options. As expected, MATE is still broken. I rebooted and tried "Ubuntu (Default)" and there were no issues whatsoever. I opened a few apps and all of them displayed OK, and used inxi -G to verify that the display server was indeed X. I rebooted again to test "Ubuntu on Wayland" and it behaved as expected too. Whatever's going wrong, it's limited to MATE, as even GNOME on X is fine.
