User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.0b8pre) Gecko/20101208 Firefox/4.0b8pre Build Identifier: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.0b8pre) Gecko/20101208 Firefox/4.0b8pre I first noticed this while loading a page with a large number of PNGs with fairly large sizes. I've noticed the same kind of issue for a while now in Fx4 nightlies. If you begin loading the page with images, stop it partway through, then hit reload, the rest of the image will load incorrectly. Reproducible: Always Steps to Reproduce: 1. Visit a page with large PNG images (example 1; http://forums.techpowerup.com/showthread.php?t=116061&page=3 Example 2; http://forums.hologfx.com/index.php?topic=105 Example 3; http://jayn0.deviantart.com/art/Halo-Reach-Perspective-176979898) 2. Wait for the images to load partially 3. Stop the page loading before they have finished loading 4. Hit reload Actual Results: Top parts of the image will be correct, the rest will appear to continue loading but will display incorrectly. Expected Results: Images should appear as usual, possibly after reloading from the beginning of the image This doesn't just happen upon being forced; it can also happen on a natural page load, especially when working with a slow or overloaded network. This is what happened to me previously. Some images loaded fine, but others stopped loading part way through. When I hit the reload button the issue presented itself. (By the way, this is my first bug submission, so hopefully I did good!)
Created attachment 496538 [details] Screenshot of the issue as seen in example 3 As seen here; http://jayn0.deviantart.com/art/Halo-Reach-Perspective-176979898
Confirmed on Linux (Ubuntu 10.10 x86_64) -- I hit this the second time I tried the STR at the deviantart URL. (I had to artificially limit my connection speed with the command "sudo wondershaper eth0 100 100" so the image wouldn't just load instantly. :) ) Mozilla/5.0 (X11; Linux x86_64; rv:2.0b8pre) Gecko/20101208 Firefox/4.0b8pre

NOTE: after I got the above screenshot, the image was busted *in my image cache* -- so I'd get the exact same busted image (loading instantly, from cache) if I tried to view the image directly or reload the forum page. I had to shift-reload the image (or any page that uses it) in order to purge the busted version from my cache.
Indeed, it definitely seems to have some kind of effect on the cached version of the images. Forgot to mention that. Possible that the cache could be the/a part of the cause?

This is potentially a dup of bug 617123.
I'm going to say that it is a dup of that bug. If it turns out not to be, please reopen.
