Created attachment 650089 [details] bug.png User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:14.0) Gecko/20100101 Firefox/14.0.1 Build ID: 20120713224749 Steps to reproduce: Opened the page: http://blobby.sf.net on an Ubuntu 12.04 with Firefox 14.0.1 Actual results: The drawing of http://blobby.sf.net/img/bg.img is not correct. The colors are wrong. If you download the actual image bg.png and compare it with the drawing of the http://blobby.sf.net page the colors are different. See attachment. Expected results: Same colors on page http://blobby.sf.net and the actual image http://blobby.sf.net/img/bg.img.
What happens if you set gfx.color_management.mode to false in about:config http://blobby.sf.net/img/bg.img is a 404
I'm sorry the right url is http://blobby.sf.net/img/bg.png .
It is an integer so i set it to 0. Than everything works fine:). Thank you! But I think its a bug anyway.
0 is right, that disables the color management. It's either a bug in the embedded color profile or your system/graphic card driver if disabling the color management makes it work
lspci says I have an IntelGM965 graphic card.
Looks like a dupe of bug #621474
Looks like a dupe of bug #621474. PNG images marked with the sRGB tag (such as this "bg.png") are rendered as sRGB while HTML colors are rendered as gamma=1/2.2 which is a close approximation but not exactly sRGB. When you display both on the same page, a faint difference is observable.
