 actually
DRI2CanFlip() which failed, because the window pixmap is not the screen pix=
map.
This turned out to be because SDL 1.2 enables backing store when supported:

Even if awesomenauts doesn't use SDL 1.2, it might be worth disabling backi=

store via

 Option "BackingStore" "off"

in xorg.conf or the -bs Xorg command line switch.
