I'am using PhpStorm 2017.2.4 under Debian 9.2 64bit. In the Editor window, on the left side the 'I' bar is not showing up, instead the default cursor is shown. On the right hand side of the editor, it is shown, but it is also shown when above the scrollbar. I deleted the whole PhpStorm Installation and config and reinstalled it but nothing changes. After deleting the projects .idea folder the problem is gone for 1 hour or 2. After that the Problem reappears. It is like the area where the 'I'-Beam should be shown is shifted to the right hand side. If you like, I can provide Images or the .idea log. What can I do to fix this, do you have a advice for me?
