Version: 3.4.2 (using KDE 4.4.2) OS: Linux Installed from: Ubuntu Packages When opening a big 'compressed' js file Kate stalls (depending on the size, it may take a few minutes of 100% CPU before the file is shown). Once the file is shown, Kate stays completely unresponsive and is hard to use and terminate. reproduce: - open http://download.dojotoolkit.org/release-1.4.2/dojo.js (27kB) expected: - the file is opened and Kate stays responsive _or_ Kate shows a warning that the file is "really big" which it isn't actual: - Kate stalls The problem is a bug b/c even though it is unnatural to open a compressed js file, it's something happening in the day to day life of a web developer b/c one doesn't know the content of each file before opening it. Either way, Kate shouldn't stall. I suppose there's a too high complexity when it comes to parsing (extremely) long lines since opening the same js files 'uncompressed' works almost instantly and as expected.
known issue. This is because of very long lines. Qt has to layout the entire line because it might contain bi-directional text. No way around it... *** This bug has been marked as a duplicate of bug 225228 ***
