Hi, you need to update your Kate version and try again. I have put in a few fixes for this issue in the latest release and the one before that.

To try the latest, you'll have to build it yourself which is pretty easy to do on debian unstable. Pasting the instructions below:
- Install build dependencies of kate and build essential tools (gcc, cmake) from distro packages
- Clone kate git repo: https://invent.kde.org/utilities/kate/
- cd kate
- mkdir build && cd build
- cmake .. && make -j4

Once the above finishes successfully the kate binary can be found in the 'bin' subdirectory. Run `./bin/kate`

If the latest one is also slow, please reopen the issue.
