Thanks for the info and LO Bug Report @xhanssx . 
Can you try one more thing?
- Uninstall Collabora Office.
- Reinstall Collabora Office.
I actually brought your topic up during last week’s “Collabora Community Weekly” meeting… and it reminded me of these recent topics too:
- /r/LibreOffice: “Insane lag on Macbook M1 after the last update (ver 24.2)”
- User solved by uninstall/reinstall.
Or this user’s comment 2 months ago:
Looks like quite a few other recent Mac users have been having strange “slowness” issues on LO 24.2 too.
Hmmm…
And yes, like @mmeeks said, hopefully the soon-to-be-released 24.04 will fix a lot of this for you.
Great to hear. Welcome aboard!
