Laggy Sandbox UI

Describe the bug
My Sandbox has multi-second UI lag and has had so for several days, persisting over restarts. It seems to be getting worse. Chrome profile of some typing attached.

This seems to be related to the git plugin, and having lots of untracked files

@MatthewJA is this still a problem? Is it reproducible? Is it browser independent?
