I did not experience this on 16.04/16.10 and IIRC not even on 17.04. After a lot of hit and trial, I was able to fix the issue completely by disabling Intel PSR mode in Grub config. Change `i915.enable_psr=1` to `i915.enable_psr=0` in `/boot/grub/grub.cfg` fixed the problem for me but I think this disables some power saving features.
