This looks like a canvas page. Can you please try this:

1) go to about:config
2) Set the preference "gfx.canvas.azure.accelerated" to false.
3) Restart firefox. Does this still happen?

I can't personally reproduce this. Thanks!

I guess thta is the hardware acceleration setting, right?

I tried that yesterday at mconley suggestion and it fixed the problem .

Did you disable e10s / multi-process nightly? Your about support says no APZ, which is odd.

Also, does this happen every time you load the page or only sometimes? Thanks!

I did disable e10s. 
It doesn't happen after I changed the settings, even going back to same state now.
