I think the demo of KB: Armored Princess contains Starforce, that's why it
doesn't start in Wine, but it would be a good "benchmark" for this issue,
because it has an animated background in the menu.

As for KB: The Legend, the slowdown can be seen right in the tutorial, when you
start a new game. With shadows disabled both 1.1.42 and 1.1.43 gives nearly the
same performance. The difference is visible when shadows are on 'normal'
setting: with 1.1.42, well, it's slightly below the playable level on my
hardware. With 1.1.43 the situation relapsed: as if I could see still images.
I guess the issue is more noticeable for me, because of my low-end hardware.
I used 'normal' settings in every graphical options, with FSAA disabled.

Anyway, does it matter if I compiled 1.1.43 with cflags -O0 this time? 1.1.42
was compiled with the default -O2. Might it cause the performance loss when
shadows are enabled?
