SUMMARY
I use Kate on macOS more than a year, constantly upgrading to the latest stable versions. Now I've upgraded to 24.05 (installed from .dmg provided at KDE CDN) and I notice that application response is worse than it was. When I click in different split window, create new document (Cmd-N), call saving dialog (Cmd-S), everytime I have to wait a few seconds to start typing.

I tried to upgrade to nightly release (master) from 2024-06-03 and there is the same issue. I also tried to open different session (no opened documents) and the response of application didn't change much. Downgrading to 24.02 helped to restore the previous performance.

STEPS TO REPRODUCE
1. Install Kate 24.05 and start the application
2. Create a new document (takes seconds)
3. Go to View -> Split View -> Split Vertical
4. Create a new document Cmd-N
5. Click into another split window and try to type (app is waiting and first letters appear a few seconds later)
4. Save the document Cmd-S (it takes a few second to open save dialog)

OBSERVED RESULT
Kate application has to wait before a requested action is executed.

EXPECTED RESULT
Kate application almost instantly does what I request.

SOFTWARE/OS VERSIONS
macOS: Sonoma 14.5

Can you try the current nightly?

https://kate-editor.org/get-it/

I think I should have fixed a lot of issues with the Frameworks 6.3 that are used there now.

I confirm that kate version 24.07.70 (nightly from 2024-06-11) works fine.

Thank you.

Nice, sorry for the regression, I hope the next stable release will continue to have the current performance.
