Clicking on the toolbar changes the mouse focus incorrectly
so you can't do mouse clicks anymore.
How to reproduce:
Click with the primary mouse button on the toolbar.
After releasing the mouse button
the cursor should change to its default state again.
The cursor remains in the wrong state ("fist").
Only a mouse wheel click resets it.
Simple test case is attached.
Bug is not occuring with Gnome 3 so it's not a GTK+ issue.
Duplicate of https://bugzilla.xfce.org/show_bug.cgi?id=8949 ?
No, this is not a duplicate of my second bug report.
The actual behaviour is still the same,
even if the patch from Olivier Fourdan is applied to xfwm4.
A workaround is to use
"gtk_widget_set_valign (scale, GTK_ALIGN_CENTER);"
but the mouse focus should not change at all.
The intention for the hack in scale_press/release became the default behaviour in recent versions of GTK3. I have tested GTK+ 3.8.2 without the scale hack and can't reproduce this bug anymore.
