The bug has been fixed upstream. While the Linux foundation is taking care of
some of the backporting of fixes, invasive fixes are not going to be
backported. As far as we are concerned, the latest LTS kernel is working, so
that's all we can commit to.

Thanks for reporting back!

PS: have you tried using the modesetting driver? I am adding support right now
for TearFree if this is what prevented you from using it.
