This doesn't look significant enough (user experience, rather old if Firefox 23 is correct) to warrant taking at the end of the 33 cycle. I'm going to track for 34+ and get the gfx team to weigh in on this one.

I'm a little surprised this would be related to OMTC. I'll have a look.
Bas - Were you able to look into this?
(In reply to Lawrence Mandel [:lmandel] (use needinfo) from comment #7) > Bas - Were you able to look into this? Not yet, there's sadly a long list of more important OMTC bugs we're still investigating.
If I was guessing, I'd first check if it's one of those repeat vs. clamp to edge vs. clamp to border issues...
This is lower priority than other bugs for 34. I'm leaving this tracked for future releases.

too late in the 35 cycle now, and fortunately this is cosmetic and not functional breakage. wontfixing for 35 and leaving tracking for one more cycle.

No activity, we shipped several releases with this bug. I am not sure it is worth tracking anymore...

I suspect is a page zoom of 1.25 in the screenshot (the line is 250px from the left edge of the canvas, and the canvas is 200 CSS pixels wide). So this look like the right edge of the CanvasLayer samples from its left edge during scaled composition.
FYI, I can reproduce on Firefox35 win32 w/ HWA. However, I cannot reproduce on Firefox36, 37, 38.0a2 and 39.0a1 win32 w/ HWA.
Fixed on my side too. Working range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=a255a234946e&tochange=7e3c85754d32 Probably fixed by bug 1088417.
