I solved disabling overlay scrollbar

This commnand:
gsettings set com.canonical.desktop.interface scrollbar-mode normal

[fabianbur (fabianbur)]

But the window has a strange behavior with some blur to resize.
Also it lose the overlay feature. It is there that is the problem I think.

The kernel was updated today to version 4.4
Calibre continues to fail

[Ruairi (ruhann)]

I have the same issue. Shows the welcome screen only. Launching from a terminal shows

"(python2.7:2300): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion 'GTK_IS_WIDGET (widget)' failed"

repeately. Followed by

"Segmentation fault (core dumped)"

[Ruairi (ruhann)]

I can also confirm that fabianburs fix

gsettings set com.canonical.desktop.interface scrollbar-mode normal

resolved the issue for me.

This moment is fixed the bug
