Describe the problem

Oftentimes after clearing a song I get 3-4 seconds (or longer) pauses when leaving the gameplay screen. It doesn't happen 100% of the time but it is frequent. I haven't reproduced the issue with the default theme yet (but I have given it just a few tries, I never use default). I think this is an old problem. It happened to me back in 2021-09-04 (using latest OutFox release at that time), but maybe less frequent at that time (smaller Stats.xml ?).

I have attached logs I copied just after the freeze happened. I have checked the "theme errors" (that can be displayed using the debug menu, "Show recent errors") but nothing was shown there.

Please note that I am using Dropbox to keep my scores synced and backuped. I got to think about it some more, and I'm strongly suspecting OF is trying to acquire a lock after Dropbox has put a lock on the file (for uploading after last change). Since duplicates appeared in my Stats.xml at some point and it grew huge (10MB), it would explain why I am starting to notice these delays more and more (though I would expect even more delay than that, considering I have got around 500KB/s upload speed). Sorry for the useless bug report if this theory is true. I will try to confirm it.

We cannot write to a file that is locked, so the main thread will hang until the lock is released.

You should turn off Dropbox when playing as it can cause dual entries and corruption.
