Changes to the source code of the driver are controlled via Git as commits.
Assuming it once worked 144 Hz it's possible to use Git to find out which
commit caused the flickering. This is done by identifying any commit which
worked (good, in your case 4.4) and a commit which doesn't work (bad, 4.8).
Bisecting will then help you find the first bad commit faster (by sectioning
the pool of possible first bad commits in two sections repeatedly).

I'm not sure though that this good commit exists though. Flickering also
happens with 4.4 for me.
