Sorry, those most recent comments led to me forget that this is about Wayland. But actually you can use Wayland with the official Nvidia driver, and it might resolve the bug. You need to make a couple of tweaks to reveal the Wayland login option after installing the Nvidia driver:
1. In /etc/default/grub add the kernel parameter: nvidia-drm.modeset=1 2. Comment out the Nvidia rule that is disabling Wayland in /usr/lib/udev/rules.d/61-gdm.rules -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1905270 Title: [HP OMEN Laptop 15-en0xxx] [amdgpu] [nouveau] On any external monitors, wayland session has a white block on most part of the screen.
