A sample presentation which animation fails to play with HW acceleration
enabled

Some animations fail to show on presentation screen when hardware acceleration
is enabled [1]. This happens on Linux; I couldn't reproduce that on Windows.

An example is in the attachment.

Screencast: http://youtu.be/Kju3_B4eF1Y?hd=1 (it's shown that on dual monitor
configuration, the animation plays on Presenter Console fine both with and
without acceleration, while on presentation screen, the animation is only
visible with acceleration off).

Reproducible with:

Version: 5.4.2.2
Build ID: 1:5.4.2~rc2-0ubuntu0.16.04.1~lo2
CPU threads: 2; OS: Linux 4.4; UI render: default; VCL: gtk2; 
Locale: en-US (en_US.UTF-8); Calc: group

and Version: 5.4.3.2
Build ID: 1:5.4.3~rc2-0ubuntu0.16.04.1~lo1
CPU threads: 2; OS: Linux 4.4; UI render: default; VCL: gtk2;
