User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150305021524

Steps to reproduce:

No apparent cause, happens completely at random.

Actual results:

The screen will flash briefly, anywhere from a fraction of second to a full second, with green, red and or black lines and shapes (i.e. rectangles, triangles, basic squares with added 45-90 angles). Sometimes the entire window goes black with green or red lines/shapes overlayed. So far It's happened mostly in the upper left corner, although have seen it once in upper right. Happens completely at random, extremely fast and nothing I've done indicates I can manually recreate the process. Problem started occurring recently (maybe around 03/12/2015).
Happens so quickly I can't possibly screenshot it.

Expected results:

More like what SHOULDN'T have happened, and that's the bug I am reporting! :)

Also, it appears to be strictly a graphical corruption, as absolutely nothing seems effected by the glitch, firefox continues to operate normally otherwise.

That smells graphics issue, maybe driver incompatibility with Win 10.

Honestly, as Win 10 has not been released yet, don't expect any fix if it's a Firefox issue, because many bugs from Win 10 will be fixed before its release date.

Could you paste the "graphics" section from the page about:support please.

Is it the latest driver provided by AMD to work with Win 10?

Got a screen shot of another glitch, this is more akin to the one I first mentioned:

Yeah, typical AMD driver issue.
We should keep an eye out for similar bugs, and see if they are specific to Windows 10.
