Confirmed, Hyatt has been busy in this area lately, cc-ing him, perhaps he knows how to solve this. Gonna check if this is a regression as well. This is NOT a regression, it was slow in released Safari as well. This is a bug in ImageIO. It works fine with the Win32 Cairo decoder. I will file a bug in Radar and then we can close this out. This bug still affects Safari 3.0.4 on Mac OS X 10.4. I'm not sure about 10.5, but I doubt the ImageIO bug is going to be fixed in 10.4 now. Isn't it possible to use a different decoder/renderer for GIFs, at least in 10.4? The code used in Safari 1.x on OS X 10.3 didn't have this issue; perhaps it's time to resurrect it. The original test case is not available at bug URL anymore, we cannot proceed without a test case. Created attachment 19989 [details]

Slow animated gif performance on all Safari 3+, Tiger, Leopard, and WinXP.
I believe this is a bug in the Image I/O framework and not a WebKit bug. This could be confirmed by testing this image in the GTK or Qt or wx ports of WebKit. I am closing this bug, as it is not a bug in WebKit itself (and therefore will be tracked in Radar instead of here). |
