Take a look at http://home.dipswitch.com. Notice the animated background. The latest version of mozilla refreshes animated GIF backgrounds every second.

Re-assinged to pnunn@netscape.com. Pam, do you have any idea who should get this bug? Someone in layout maybe?
In an attempt to reproduce the problem I generated: http://jazz/users/pnunn/publish/anibkgif.html to replace http://www.dipswitch.com
My test page does show the problem. Interestingly enough, an animated gif in table bkground works, but a page bkground does not. -pn
The bkground image animation does work sometimes. So its an intermittant bug. (pn: note to self:?timer/layout related problem?)

beppe...can you put in a QA Contact please to check this with latest build? Thanks!
Just check this on linux 02-23-99 build and it all animates but very very very slowly. very. fyi, -pn

On Mac OS (4.26.99 build), Seamonkey performs the animation on Jazz at approximately half the speed of Communicator 4.5 on the same system (about 5.5 seconds per iteration on Seamonkey, versus about 2 seconds on 4.5). (The speed is equivalent to Communicator 4.5 on Win32 & Linux. Also, on Linux, there's a 6th column of animated moons that appears to the right of the table, flickering on and off. If it's still present when this is actually fixed, I'll go ahead and break it into a separate bug. Thanks!)

I don't see this problem. marking worksforme. ps. it looks like the extra "moon" column is fixed too. -pn
Status: RESOLVED → REOPENED
Re-opening; the application behavior is unchanged from the 4.26.99 comment that I tossed in. To reproduce, take a Macintosh, go to the test page (I'm using a full 1024x768, window, 16-bit video), and compare the animation speed in Gecko vs. Communicator; it's about 4 seconds per cycle on Communicator, but about 8-10 seconds per cycle on Gecko.

(And, yes, I'm still seeing the flashing moon on Linux, too, although only for the first few cycles; let me know if you'd like me to show it to you.)
Summary: Animated Backgrounds → [PP] Animated Backgrounds are 2X slower on Mac OS then other platforms
I've now broken down the moon issue from 4.26.99 comment into bug #6302. (strangely enough, I'm listening to "Over the Moon" from Rent while typing the above... ;)
Target Milestone: M6 → M11
I'm pushing this bug out. crashers get priority over performance. -pn
?Could this be because NU_Cache is not enabled for mac? -pn
