Version: (using KDE KDE 3.1.2) Installed from: Gentoo Packages Compiler: 3.2.2 CFLAGS="-march=pentium4 -Os -pipe -fomit-frame-pointer -fPIC -mfpmath=sse,387" OS: Linux I recently noticed that Konqueror isn't decoding some JPEGs properly. Some parts are blocky where they are supposed to be smooth. I am currently using KDE 3.1.2. I have tested 3.1.1 and 3.1.2. Both exhibit the bug. One picture I have found that demonstrates this problem can be found at http://www.emutalk.net/showthread.php?s=&threadid=12952 as the second picture in the thread. Mozilla renders the image correctly.
Created attachment 1837 [details] Comparison of JPEG decoding between Konqueror and Mozilla On the left is Mozilla 1.3, on the right, Konqueror 3.1.2. Notice how the top part of Mario's hat looks blocky in Konq, but not in Mozilla. GIMP and KView both render the image correctly, the same as Mozilla.
Subject: kdelibs/khtml/misc CVS commit by mueller: enable fancy upsampling again, because otherwise people think that Konqueror is buggy. Ok, its 10% slower.. but who cares?
