GLX BadRequest on 12.04

Question

I have the same trouble running Compiz, Blender or simply typing glxgears into the terminal:

$ glxgears 
X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  136 (GLX)
  Minor opcode of failed request:  19 (X_GLXQueryServerString)
  Serial number of failed request:  12
  Current serial number in output stream:  12

Some more info about my system:

$ uname -r
3.2.0-27-generic
$ arch
x86_64
$ lspci | grep -i graphic
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
$ lsmod | grep -i video
uvcvideo               72627  0 
videodev               98259  1 uvcvideo
v4l2_compat_ioctl32    17128  1 videodev
video                  19596  1 i915

Also, I'm running 12.04 and my Video Card is an ATI Mobility Radeon HD 4550 Graphics.

Can anyone help me? Is there any other info you need to help me solve the problem?
