          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal

        ReportedBy: [e-mail]

I've got some graphics errors with "Falcon 4.0AF".
Quite often, when there is some gnome-notification or I minimize the game, it
seems to mix it's textures/texture indexes. There is no related output on the
default command line?
Here's some screenshot after the app lost focus: http://tinyurl.com/y9dh2fh
I will add some logfiles later, one without being messed up and one created
when intercepting the bug.

I looked around a while now, but I simply don't know what to google for. There
has to be such a bug already!?
