I can reproduce this in older builds with the unsure regression range:
Last good nightly: 2012-09-28
First bad nightly: 2012-09-29

Pushlog:

but it works for me with

bug 801784

Comment 4

Reporter, you reported this previous bug (bug 786585), is it similar?

Comment 5

[Mayank Bansal]

No, #786585 is different.

This bug is almost a dupe of https://bugzilla.mozilla.org/show_bug.cgi?id=801784 .  Though i dont know why i am still able to reproduce this issue.

Comment 6

[Matt Woodrow (:mattwoodrow)]

This works for me too, and definitely seems very similar to bug 801784. Very weird that it still occurs for you though.

i can reproduce in a new profile. I tried switching off layers acceleration and azure content. But no go.

I can reproduce it from a new profile in Windows 8 with a blocklisted graphic driver, i.e. no hardware acceleration. The driver is Catalyst 12.6 legacy, which is the latest one available for my old ATI HD3650 card.

Right-clicking and moving the cursor into context menu stops the gif animation, but another right-clicking would resume the animation.

However, the behaviour is different in my main profile. The gif animation only halts for about 0.5 seconds every time I move the cursor into or out of the context menu area, while keeping the menu opened at all times.

I have force enable direct2d and layer acceleration in this profile by setting gfx.direct2d.force-enabled and layers.acceleration.force-enabled to true, but the result is still the same (0.5s halt) even if I reset both of them to false.

This has mostly been solved by bug 808466 except for one thing :  When you click-and-hold the mouse pointer on the window frame, the GIF stops animating for ~ 1 second.

Comment 11

[Mayank Bansal]

i think this bug  should be marked resolved fixed by bug 808466

Comment 12

[Mayank Bansal]

oops. Apparently i dont have permission to mark bugs as resolved fixed.

Comment 13

[Matthias Versen [:Matti]]

Either it's a dupe of that bug or it's wfm if you are unsure

Comment 14

[Mayank Bansal]

a dupe, then.
