Comment # 2 on bug 90264 from falaca@gmail.com

Michel, I just tested it right now, and there is no corruption when I set
LIBGL_ALWAYS_SOFTWARE=1.

The screenshot I linked to is from the glowing-bear web IRC client, and I just
need to mouse over 2 or 3 items before the corruption shows up, so it should be
pretty easy for anybody else to reproduce with Chrome.

Further info: I'm running linux 3.19, Xorg 1.17.1, and both mesa & DDX from
git.
