Comment 14 for bug 1527053

There are two more issues on Ubuntu associated with gtk2-vs-gtk3 behavior.
First is missing global menu and HUD in gtk3. Nonoperability of the global menu is clearly seen in the screenshot attached to this bug report.
The other is broken scrollbars. It is not seen on the screenshot, but the current state is that the slider within the modern gtk3-style scrollbars fills the area of the scrollbar with its color as it moves just like a paint brush.
I don't know if these issues can be considered as part of this bug or should be considered as separate bugs?

Ubuntu 15.10 x64
