I just installed Ubuntu on my Raspberry Pi 4 from the official image (for rPi). Everything seems to work just fine, except for the Google login window (and the other online accounts as well).
Any idea how to fix this / work around this?
EDIT: There is a warning in the console: "GDK is not able to create a GL context, falling back to glReadPixels (slow!)"

I just encountered this problem. Switching from wayland to xorg fixed it.
