Status: RESOLVED DUPLICATE of bug 619117

(Core :: Layout, defect)

Description

[Michael Yoshitaka Erlewine [:mitcho]]

Attachment: Display artifacts in my browser

CSS transitions leave some artifacts behind of translated or scaled objects. 

Attached is a video of the Robert Nyman demo. This is a debug m-c build from earlier today.

The same demo does not produce such artifacts in Chrome or Safari on my machine.

I'm able to reproduce this (though my artifacts are a bit smaller). Mine is a debug m-c build, too. I'm running linux with an nvidia graphic card.

Graphics section from about:support says:

GPU Accelerated Windows: 0/1

I think this is the same as bug 619117. Until I confirm I'll leave this open.

Note: the situation is exactly the same for me, whether layers.accelerate-all is true or false.

And it regressed at the same time as bug 619117, so almost certainly the same bug.

I can repro gross artifacts on desktop linux by putting a focus ring around the images (mouse over it, click down, mouse off, release click) and expanding/collapsing them with further mouseovers.
