User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20050210 Firefox/1.0 (Debian package 1.0+dfsg.1-6) Build Identifier: Firefox 1.0.1 A user of Mac OS X 10.3.4, Firefox 1.0.1 tells me that http://www.aetion.com/images/logo.png looks wrong to him in Firefox, although that PNG looks fine with other Mac image viewers. I don't have a Mac, but it also looks fine to me from Windows and Linux. Reproducible: Always Steps to Reproduce: Start up Firefox 1.0.1 on Mac OS X 10.3.4. Take a look at http://www.aetion.com/images/logo.png To see how it should look, look at that PNG with something else. Actual Results: The image looked "corrupted" Expected Results: The software should have rendered the image just like other viewers of it do. The bug was reported to me by Chris Ball, copied on this report. He is cjb at mrao dot cam dot ac dot uk.
The user could have a corrupted image in browser cache. Try Shift + Reload on the image. If that doesn't fix it, please attach a screenshot of the rendering.
Apparently, Shift-Reload doesn't solve the problem. I got the user to send me a screenshot - as you can see, he sent one for http://www.aetion.com/jobs.html which uses the same logo.png graphic. (He reports that the problem is the same when he looks at just the png.) I also asked him for the User Agent string for his browser. It's Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1.
Does the problem go away in a nightly build? Does it only occur with colors set to thousands in system prefs?
(In reply to comment #4) > Does the problem go away in a nightly build? Does it only occur with colors set > to thousands in system prefs? Good catch -- it does indeed only occur with colours set to thousands. I can't test with the disk image of yesterday's nightly build, since it launches and then disappears from my process list immediately, even when run with -ProfileManager. That'll have to be a separate bug. :) - Chris.
So what does "wrong" or "corrupted" mean here? Is the image just being dithered because of the limited color space?
This looks like one of our old QuickDraw bugs. The reporter should try a recent nightly trunk build.
