See attached screenshot.  After submitting an issue on github, text was improperly placed in the lower left of the screen. Upon opening the dev tools, the bad text disappeared.  I assume opening the dev tools triggers a repaint.  Also, I've been seeing a lot of gfx glitches lately, see also: https://bugzilla.mozilla.org/show_bug.cgi?id=1145951

From what I can see this appears to be a tiling artifact, Nick, can you tell where this bled content was coming from?

Sure, to me there appears to be two bled tiles.

The right one "add)" is from significantly higher up in the page:

oh, the left one is directly to the right of the left's original content.  The sentence is
"add) these predefined headers."  It's interesting that the tiles appear swapped (left vs right).

Is this reproducible?

It looks like we've taken an old tile (or two) and recycled them but without repainting them with the new content.

I've only ever seen it once.
