Strange artifacts in trees

Hi,

When playing Dota 2, randomly and depending on the ligh and the perspective,
some random artifacts appear in trees. They also appear in other places, but
the trees are the most visible ones.

My graphics card is an AMD HD5470M (AMD Cedar) and I am using Arch linux 64
bits and mesa compiled from git at commit 356aff3.

I thought this problem could be related to this other bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=72895 but applying that patch
doesn't help.

The attached screenshot shows the problem with the trees.

If you need anything else, just ask.
