984396 - High power consumption on animation from old Vimeo homepage (no video)

Status: RESOLVED INCOMPLETE

(Core :: Graphics: Canvas2D, defect)

Description

[Roberto Agostino Vitillo (:rvitillo)]

Idling on the vimeo homepage seems to consume significantly more energy than on IE.

Attachment: Testcase 1

The power profile on http://people.mozilla.org/~rvitillo/dashboard/#vimeo shows that the GPU power consumption of FF is about 7 times greater than IE. The culprit seems to be the canvas based particle generator shown in the testcase.

I tested the animation (which doesn't appear to no longer be on the vimeo.com homepage) on Mac.

We do quite badly. In particular we hit the GPU a lot harder than Chrome and Safari.

All the testcases don't work anymore so it's hard to say if that is still a problem with recent versions of Firefox. As such closing the bug as incomplete.
