The ~/.config/cursor folder (or $XDG_CONFIG_HOME/cursor) is used for caching (cachedData). This is not compliant with the XDG spec, as the the ~/.cache folder (or $XDG_CACHE_HOME) should be used for caching. The reasons I am making this issue, is because the fact that Cursor uses the config folder for caching makes backups harder. The ~/.config folder should be backed up on Linux and it now contains gigabytes of caching data.
