Created attachment 486091 [details] Test case This only happens on nightlies, not the betas or 3.6 (or Google Chrome). STR: See attached page Expected: canvas drawn image doesn't move Actual: canvas drawn image shifts left and right with respect to canvas element
i see the using 3.6.7 on the mac. I also noticed that the canvas isn't really the thing shifting back and forth, but rather the document itself. You can verify this by zooming into the page until there is a scrollbar. Then notice that the scroll indicator shows the document moving to the left and to the right.
In nightly, it is weird that only the drawn image moves and not the canvas background.
In 3.6.11, I see the "Expected" behavior in the test case.

bz, could you try resizing your window, and maximizing it? It really isn't str yet, but I think I don't see the problem anymore after doing that.

Ah, if I maximize the window I see the jiggle. Depending on the zoom level it looks like background jiggles too, in some cases, but not in others.... So that may just be a rounding issue of some sort.
