Public bug reported:

Hello,

while using Saucy for productive work I discovered a regression
regarding scrolling.

How to reproduce:

- boot Saucy release live image (or an installed version)
- open a window of a GTK3 application (gedit, nautilus, audacious - which one doesn't matter) whose window contains scrollbars (e.g. a larger text file in gedit)
- open a second window (doesn't matter if this is also from a GTK3 app) and bring it upfront, so that it is focused (and mind that it does not completely overlap the first window, e.g. by arranging them side by side)
- Now move the mouse cursor over the overlapping part of the unfocused GTK3 window and try to scroll with the mouse wheel. It doesn't work anymore. Scrolling under those conditions has worked under all previous Ubuntu versions that I know.

Scrolling does still work if the unfocused windows is _not_ a GTK3
window, e.g. GTK2-based Firefox. Thus I assume this is not an intented
new configuration change, but a bug.

This happens independent of overlay scrollbars enabled or disabled and
independent of the chosen GTK3 theme (also with e.g. Adwaita theme).

Further investigation showed that if I use e.g. Saucy Ubuntu Gnome
Remix/Xubuntu live image, this bug does _not_ appear. It seems that the
bug can be tracked down to Compiz, because when I run XFCE and start
Compiz manually, the bug also appears, thus it is not dependent on
Unity. On the other hand, with other window manager like XFWM4/Mutter, I
can't reproduce the bug.

Kind regards,
Jan
