Please do this with hardware acceleration enabled. Please also attach a screenshot of the bug if you can.
Screenshot is a bit problematic would not show up on that would have to make a video. For it to show up.
Here is a video of the problem:

goes away when Hardware acceleration is turned off in Browser menu.

Thanks! Please reenable hardware acceleration, open about:config, set gfx.webrender.compositor to false, restart Firefox and check if that is enough to fix the problem.

We'll probably wait for the dual screen flicker (bug 1638709) issue to be resolved before doing anything about this one.

Can you test with the latest GeForce 461.72 driver?

There is a similar sounding bug affecting NVIDIA GPUs on the Chrome bug tracker - https://bugs.chromium.org/p/chromium/issues/detail?id=1185538.
Would you be able to temporarily apply the test workaround mentioned in that bug (https://bugs.chromium.org/p/chromium/issues/detail?id=1185538#c10) and let us know if that resolves the issue you're seeing?
That will allow us to know if we're looking at the same underlying bug or if this is something different.
