Smooth scrolling in Mac

This seems to be a recurrent topic but it still severly hampers my working with LibreOffice on Mac: The scrolling with the (magic) mouse is laggy and not as smooth as in all other applications. I searched a lot and some people seem to have the same problem (already years ago), some replies say LibreOffice just is slow on Mac (StarOffice would be better). On another Macbook, however, the scrolling with the touchpad works just fine (this with LO version 5). With version 6 on my iMac, I just updated to 6.1, it is hardly bearable. There are no other performance issues. Please don’t tell me it has to do with OS mouse settings. All other applications work like a charm. If filing a bug would help I can do that as well.
Any help is really appreciated!

I also have the same problem. And with typing too. Looks like a few people have this issue but it isn’t going to be resolved. Turned off Open GL, etc. Running v. 6.3.3.2 on Mac OS 10.13.6.
