This test case tests whether accelerated OpenGL applications under compositing managers work with the llvm-softpipe video driver.


  1. Ensure that Package-x-generic-16.pnggnome-shell and related packages are installed by running the command: su -c "yum install gnome-shell desktop-effects"
  2. Ensure the Package-x-generic-16.pngglx-utils package is installed by running the command: su -c "yum install glx-utils"

How to test

  1. Run the command glxgears (or, optionally, any other OpenGL app you can think of)
  2. Try covering the glxgears window with other windows
  3. Move the glxgears window around
  4. Activate the Shell's overview mode (press the Super (aka Windows) key, or move the mouse to the top left hand corner of the screen), and deactivate it (same procedure)

Expected Results

  1. glxgears (and other OpenGL apps) should run properly and with full acceleration and behave as any other window. Covering them should work properly, they should move smoothly, and should render properly in the overview mode. Overview mode should activate quickly with a smooth transition, and deactivate in the same way. GNOME Shell should run successfully and there should be no glitches or corruption in the display of the desktop or overview mode with GNOME Shell enabled
