Description Vitovt 2022-01-23 17:20:16 UTC 
libreoffice became increadibly slow on using emoticons (utf emoji).

Scrolling and screen updating is extremely slow.

When columns with emoji is out of screen - it works OK.

OS: Ubuntu

The same was in all previous releases including 6.x

Maybe it is KDE plasma related ?

Also I'll try to check in Windows7 today.

There was an earlier report, bug 131468, but now nobody else could reproduce it. I wonder, if it is due to operating system updates, then, as a commenter can't reproduce with 7.2.5.
Comment 6 Dan Dascalescu 2023-04-03 18:08:21 UTC 
I also have emojis in this sample, bug #153985 - maybe they are the cause of the slowness?
