I just have updated my Inkscape from inkscape.dev/stable PPA to 0.92. And I can't find this path effect! Is it exsist in PPA version, or removed? How I can get it?

I use Inkscape 0.91 from ubuntu repos, and Ubuntu Gnome 16.04 (with Gnome Shell).

I have 2 Ubuntu, one of them updated from 14.04, one installed from usb. And both of them have this problem. And I don't have any special input devices

When I click on the buttons next to the digital input several times (doubleclick), they are froze, as if I continue to hold mouse button. This is screencast:

I use Ubuntu Gnome 16.04. Can I fix this?
