Downgrading to gdm3 3.29.90 somewhat avoided the problem and reverted to bug 1786872. But when VT switching to work around that one I managed to reproduce this crash again, even with gdm3 3.29.90-2ubuntu1.
Finally got a crash report from Xwayland this time -> bug 1786914 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786883 Title: [regression] Login screen flickers to black a few times on boot and then finally settles on using Xorg instead of Wayland.
