Thanks for the bug report.
First please try disabling all extensions in the Extensions app, then
log in again.
If the bug still occurs then next edit /etc/default/grub and change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"
and then run:
sudo update-grub
and reboot.
If the bug still occurs after that then while it is happening please
run:
journalctl -b0 > journal.txt
and attach the resulting text file here.
