I am starting with a use case/user story – but I might be able to produce a simplified testcase as soon as first need is clear. The case is: * You have, let's say, scale and rotation 3d; for a DIV with text or image. Then you use, for duration, something like 100 seconds — so to expect something very very slow, therefore expecting a lot of "frames" to be produced. What I mean by frames is updates in the screen. Problem: So far I see, in Linux, the zoom/scale effect to have miscalculations — it is positioned clearly outside the shortest path to a (interpolation) target. Let's say that frame 1 is positioned X,y and frame 3 to be positioned at X' Y' — the frame 2 is slightly outside what human eye would expect as interpolation. In other words, When you record screen and animated quickly it becomes all shaky. m

Sorry it's a quick time video mp4 taken from PNG screen shots: http://www.mgalli.com/development/out-bug.mp4 Notice the "graphic logo" near the center of the screen, it's supposed to be super smooth — go frame by frame and you will see how it sort of goes to random direction among frames.

BTW the problem only happens when 3d transform is present.

Can you check whether this still happens after bug 1097776?
