OK I got ahold of a laptop with an ATI graphics card to test this.

With Ubuntu 10.04, on a laptop with an ATI Radeon HD3470 video card,
with fglrx (2:8.723.1-0ubuntu5) from the Ubuntu repositories, if I turn
on Standard desktop effects, then one of the Mixxx waveforms flickers
severely and 'ghosts' if I move the Mixxx window around (i.e. the
waveform does not move with the Mixxx window, it remains where it was
originally created). If I rapidly minimize/expand Mixxx, eventually X
freezes and I have to restart GDM. With desktop effects turned off,
Mixxx (both the 1.8 branch and trunk) run perfectly.

While running the Qt examples, it looks like the 'textures' example
shows similar results. This is likely because it is the only example
that uses multiple OpenGL contexts.

For all of you, would you please install the package 'qt4-demos' and then run the following program:
/usr/lib/qt4/examples/opengl/textures/textures

Please report whether or not the program causes a crash similar to the
way Mixxx crashes. That will help me determine whether or not we are
dealing with a Mixxx bug, a Qt bug, or an fglrx bug.

Thanks everyone,
RJ Ryan
