Flickering and a lack of smoothness are two different issues. The lack
of smoothness would just be due to your GPU staying at a lower frequency
more often, so it's not a bug but something you would need to tune
yourself.
As for the flickering, please 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 problem still happens after that then while it is happening,
please run:
journalctl -b0 > journal.txt
and attach the resulting text file here along with a video of the
flickering problem.
