I have a two monitor setup, using an RX 480 for my main monitor and the iGPU for my second (the reson is a whole other issue with AMD drivers). After I installed the intel graphics drivers my mouse started laging. First I installed the Beta 220.127.116.1174 drivers and the mouse lagged continuesly to the extent where I could barely do anything with it (had to use my keyboard to reboot). After that I completely removed AMD and Intel drivers and reinstalled, this time I installed the stable 18.104.22.16863 version of the drivers and the mouse lag only happend very sporedicaly (usualy when I try to move it just a little) and is hardly noticable.
EDIT: it can get pretty bad on the stable drivers aswell
Often (51-99%): X (beta drivers)
Very Sporadic (<20%): X (stable drivers)
