Creepy Artifacts

This has been happening off and on for a while now. Every so often some element or image with text when scrolling creates this construction paper patchwork artifacts. I haven't seen it anywhere else in any other major browser.

Another Example
Does it go away if you set gfx.direct2d.disabled to true in about:config?

Its hard to pin down because the corruption happens randomly. I'll try the d2d toggle the next time I see it.

I been getting this, same thing as the attached picture by Bennet.  Been obsessing over it for the past month.  I do know it is HW acceleration related, b/c it doesn't happen wit it off.  I know for sure that it doesn't happen in Firefox 31 ESR for some reason, but it happened in Firefox 33, and now 34 and up it seems.   It seems to me, something changed with HW acceleration after Firefox 31. 

It also happens randomly for me, but more frequently waking the computer after sleep.  I got a new r9 290 this December, before I had a older Nvidia card 460 gtx and I never ran into anything like this, worked perfectly as far as Firefox is concerned.  Using latest AMD drivers.
