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.
