[Daniel van Vugt <2115401@xxxxxxxxxxxxxxxxxx>]

Thanks for the bug report. The most likely explanation for this is PSR
(panel self refresh) not working. Please try disabling it by adding this
kernel parameter:  i915.enable_psr=0

You can do so by editing /etc/default/grub and setting:

  GRUB_CMDLINE_LINUX="i915.enable_psr=0"

Then run:

  sudo update-grub

and reboot.
