I've looked everywhere for a fix, but can't seem to find a way to fix this problem, or even anyone else with it.
Whenever I run Kate, I get weird underlining (which breaks easily becoming blurry, etc. if I scroll/resize the window, only redrawing when I minimize and then maximize the window).
Any other user, including root (using
kdesudo kate) doesn't have this problem.
I have tried removing Kate config files in my home directory to no avail, although every setting was reset. I have also tried enabling and disabling everything in the settings to.
No other app/user has this problem. The font settings do not have any 'underline' checkbox checked (and I've reset them to no avail even then).
This is on a 3-day old install of Kubuntu 12.10. The problem started the second time I used Kate, and has remained since...
Thanks for any help!
