Description Andrey 2008-06-10 15:42:59 UTC 
Please describe the problem:
In some animated gifs (seems, who has variable timeouts from frame to frame) timeouts processed wrongly (as identical) in result animation looks broken.

Steps to reproduce:
1. Open attached animated gif files in Opera or Firefox. See proper beautiful animation.
2. Open them in gThumb. See broken animation.


Actual results:
Animation is broken.

Expected results:
See animation as in web browsers.

Does this happen every time?
yes

Comment 4 Roman Ovseitsev 2008-07-26 18:38:48 UTC 
These gifs have their frame delay set to 0.
Firefox and opera seem to use 100ms delay for such occasions, while gthumb uses 20ms (returned by gdk_pixbuf_animation_iter_get_delay_time() for zero delay frames).
I suppose the minimal delay in gthumb could be increased but then it might worsen things for other animations?
Comment 5 Andrey 2008-07-27 05:43:01 UTC 
In theory it is, but in comparision Opera or Firefox displays animation more berrer, therefore such default settins are well-taken.
Comment 6 Michael Chudobiak 2009-03-17 14:40:21 UTC 
This has been fixed in the gif loader.
