I am experiencing a frequent but intermitten issue with PHPStorm code folding. When I open a file and fold all the code (Ctrl Shift -), after a few seconds the code unfolds and the ability to fold is gone (the + / - next to the line numbers are missing and the Ctrl Shift operations no longer work). I have to close and reopen the file to get folding back.
Files are on Ubuntu server with drives mapped using Samba
Has anyone else experienced this issue?
