Example of complex document with graphics
Mouse scrolling complex documents is painfully slow in Writer with the GTK3
interface (on Linux).
I've attached an example document to this bug report.

href="show_bug.cgi?id=104716">https://bugs.documentfoundation.org/show_bug.cgi?id=104716</a>).
To reproduce:
1. Open the attached document in Writer with the GTK3 interface and set zoom
level to 140%
2. Go to page 104 and scroll around several pages with the mouse. The scrolling
is very slow, much slower than scrlling the pages with the keyboard.
3. Open the attached document in Writer with the GTK2 interface and set zoom
level to 140%
4. Go to page 104 and scroll around several pages with the mouse. The scrolling
is now fluid.
