Are you using Wayland or Xorg?
Currently Wayland and Nouveau driver, which are the default.
When it occurs, on the GDM screen the lag is noticable already. It doesn't
make sense to log in then. The mouse pointer doesn't move cleanly. Logging
in suffers from delays. And then it becomes worse and worse. One can barely
move the mouse anymore to use GUI elements. It takes two seconds for windows
to open. Denial of service. As if something throttles graphics operations
due to not setting up the hardware properly.
When it doesn't occur, everything is fine already at the GDM screen.
