Closed Bug 448022 Opened 15 years ago Closed 15 years ago
Image embedded into an HTML page using the img tag is not displayed if not already cached
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-GB; rv:184.108.40.206) Gecko/2008070206 Firefox/3.0.1 Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-GB; rv:220.127.116.11) Gecko/2008070206 Firefox/3.0.1 When loading the URL above, the image in figure 8 isn't displayed if it is not already cached by the browser. Reproducible: Always Steps to Reproduce: 1. Empty the browser cache: Firefox -> Preferences -> Privacy -> Clear Now; deselect everything except 'Cache' and click 'Clear Private Data Now' 2. Go to http://dev.w3.org/csswg/css3-background/#the-border-radius 3. Scroll down to figure 8 4. All images on the page are displayed normally except Figure 8: this one is not visible 5. Load the image in the figure explicitly by requesting http://dev.w3.org/csswg/css3-background/smooth-radius.png 6. Click the 'back' button on the browser or go back to http://dev.w3.org/csswg/css3-background/#the-border-radius 7. Figure 8 is now displayed properly 8. Close Firefox 9. Go back to http://dev.w3.org/csswg/css3-background/#the-border-radius 10. Figure 8 is displayed properly 11. Repeat the steps above, clearing the cache first and the figure will fail to display again Actual Results: Step 4: the content of figure 8 (a PNG image) is not displayed. Expected Results: Step 4: the content of figure 8 should be displayed when the page is loaded for the first time. I have only tried on Mac OS-X Leopard so it may be limited to that platform. I cannot tell whether the image is actually loaded and just not displayed or if it is not loaded at all.
I saw only one time that the image failed to display (on Windows, using a new profile), but was not able to repeat it. Clearing cache didn't help to repeat it, here.
Ok, I see now that not Figure 8 is missing but Figure 7, so it is a All-All bug.

Could it be related to threading? And in this case, is it significant that my machine is a dual-processor box? If that's any use, here is the hardware overview of my box: Model Name: Power Mac G5 Model Identifier: PowerMac7,3 Processor Name: PowerPC G5 (3.1) Processor Speed: 2.7 GHz Number Of CPUs: 2 L2 Cache (per CPU): 512 KB Memory: 8 GB Bus Speed: 1.35 GHz Boot ROM Version: 5.2.4f1
It appears to affect fast computers more than slow computers. I can be mistaken, but it seems related to the pref network.http.max-persistent-connections-per-server. The page becomes quite a mess with the current value 6, pictures are not on the right spot and when I change it back to the value 2 like it used to be the page is not broken anymore.

Joe, can you look into this? It sounds like this server is having issues, but confirming that, and maybe why would be awesome to know what's really going on here.

Marking blocking, pending investigation.

No matter what I do, I can't reproduce this. Maybe the server has been fixed? Reporter, can you still reproduce this?
Haven't heard back in two months, so I'm marking this one incomplete. It was probably a server issue, but in case it wasn't, feel free to re-open.
