LibreDraw running slow

The Libre Draw on my machine is running supper low.
Any action (for example: switch page, move up/down/left/right, add line) I perform on a drawing would take at least 1-3 seconds for it to be executed. It’s extremely laggy.
The same drawing if performed on my colleagues’ computers, which run the exact same version of LibreDraw, would be executed instantly.
I already tried to re-install the entire suite of Libre Office a few times; however, the issue still persists.
It’s very painful for me to work in this condition.
Could someone please help?

Thank you.

Test with Menu/Help/Restart on safe mode, and use a new profile. It’s difficult that a reinstall can clean a corruption in the profile.
