5969 - performance issue with animated gifs

Status: VERIFIED DUPLICATE of bug 2148

(Core :: Graphics: ImageLib, defect, P3)

Description

[cpratt]

build id: 1999050317
platform tested: windows nt

if you go the above url, the bwglobe4.gif image has an inordinately long pause
before it animates itself again. that is, the globe spins, you wait about two
seconds, it spins again. in nav 4.6, it spins continuously. in ie 5, it spins
continuously. if you load just the image itself (http://schist/bwglobe4.gif), it
does spin continuously.

does this mean there are performance issues with animated GIFs? (I've also seen
problems at ty.com with performance.)

Hi, Chris ---

I believe this is a duplicate of 2148. If you agree with this conclusion, could
you perhaps improve the phrasing of that bug title, so that its subject matter
would be more precise? (it's very ambiguous, and I assume it didn't come up under
any searches you probably did before writing the bug report.)

Of course, if you don't agree with this conclusion, please re-open with your
comments.

Thanks!

I agree. Animated gif behavior depend on changes in netlib.
All animated gif timing issues should be held until Necko
lands.
