Had the same problem: cursor jumping in Explorer when changing names of local replication files from oneDrive / Sharepoint. Names of files and directories were changed, sometimes when renaming pdf files - new directories were created from the entries, etc. I have tried many things, including deleting all local files and rebuilding them on a newly installed hard drive - no success!
My solution ? : In addition to oneDrive /Sharepoint, a version of dropbox was also installed on this computer. I have deinstalled this dropbox version and since then it seems to have stopped
