Description
The Kate editor for KDE has serious performance problems with files that contain very long lines with highlights. Attached you find a callgrind output and a file with such a long line.
As you will see, more than 70% is spent in QTextEngine::format() alone. Can this be improved?
If you need more information, please let me know.
