I'm afraid it might be at this point, due to TearFree always incurring an
additional GPU copy.

Well, it's not quite the same, since even fullscreen windows can tear witho=
ut
page flipping. But yeah, it's possible to eliminate the additional GPU copy
while a DRI3 client is page flipping, just haven't got around to implementi=
ng
it. Anyway, that's a separate issue from the stuttering and should be track=
ed
in a separate report.

BTW, I don't suppose xf86-video-amdgpu 18.1.0 makes any difference for the
stuttering?
