Description David King 2011-06-27 17:57:21 UTC

I experience a bug in webkit-gtk, where most animated GIFs flicker and are almost impossible to view:

https://bugs.webkit.org/show_bug.cgi?id=55830
https://bugs.webkit.org/show_bug.cgi?id=55937

To reproduce, go to the GIF article at Wikipedia:

http://en.wikipedia.org/wiki/Graphics_Interchange_Format

For me, with webkit-gtk-1.2.7 on amd64 and x86, using Epiphany as a browser, the globe at the right of the page flickers severely, or does not rotate at all.

The bug was introduced by a bad marge into webkit-gtk (it was never present in Webkit trunk), and fixed by this webkit-gtk commit:

http://gitorious.org/webkitgtk/stable/commit/1c3ae92649aa57aad859484c7cbbdae69c73f6cd

This could either be fixed by adding the above patch to webkit-gtk-1.2.7, which I have tested and works as expected, or by bumping the stable webkit version to 1.4 or above. I have not tested this, but the patch is included and so should work fine.
