In my vault I have an issue in the File Explorer side panel. The folders I am working in are left with a square filet box around then. After a while there is a lot of them and It is quite disturbing.
If I close the vault and reopen it, then the boxes are gone bit they’ll come back.
I’ve tried with different themes, but this does make any difference.
I do not have that. What operating system are you on? What is the version of Obsidian? How was the software installed? Does it happen in a different vault? Try renaming the configuration folder of Obsidian, then start Obsidian again - it will create a new factory default configuration. Does it happen again?
My vault is on iClould Drive, so I followed the disabling “Optimize Mac Storage” as said in the Troubleshooting Guide and the problem has disappeared for now.
