It might be a driver issue or if you are running a source distro (i.e. Gentoo) there could be large # of problems (not knocking those, just saying).

I would suggest that you update your kernel per your distributor + video driver from your manufacturer + audio driver via it’s vendor vendor.

If it’s [b]reproducible[/b] on other peoples boxes then you should file a bug report, but only if you cannot find a solution or are certain it is not a distrobution-specific problem.

Please note that it seems as if bug reporting is a lost or dead art form these days – so may I suggest including the following information:
Linux/BSD Distribution and Release version
Kernel version
Video card Make and Model
Video drivers Version and Where obtained
Audio drivers Version and How obtained
dmesg output
lsmod output
X11 logfile
WindowManager being used
Describe how you are launching the program
State the expected result (what should happen)
State what actually occurs (what is happening that should not or deviates from the expected)

Personally I would also include these:
Your motherboard Make and Model
#of RAM installed and have you Tested your RAM for errors

There is a when and how on reporting bugs at the official site. [i]It includes how to gain more information from the executable while launching.[/i] Look under the:
