Hello,
I have used Kate under Linux for years and generally find that it does the job very nicely. However, lately, under Linux Mint 17.1 and Kate 4.14.2 I experience two annoying issues:
(1) when opening existing files the CPU-Load goes over the top and it takes ages to open files
(2) even though I use the previously active session, recently opened files are not displayed.
By the way, on my Debian-Wheezy, Kate 4.8.4-1 system everything works fine
I wonder what's wrong in the newer version!
Regards
H. Stoellinger

Hi, sorry for opening old thread but it is first result for "kate high cpu usage" keyword.

I have Ubuntu 20 x64 at the moment and got latest kate 19.12.3.

When I simply open kate without opening any files, it is using 100% of 1 core CPU all the time, anybody else is also facing this problem?
It is annoying, because my laptop is going to be much more noisy when I simply open any text file.

Does this also happen with a new user? If not, you probably have settings in katerc that cause this, see ~/.katerc

FWIW: Please always open a new thread when the previous one is older than 6 months.
