Comment 15 for bug 593380

As far as I know I'm running the classic r300c driver.

The extension "GL_ARB_texture_non_power_of_two" seems to be disabled by default and when enabling that one (MESA_EXTENSION_OVERRIDE=GL_ARB_texture_non_power_of_two unity) UNE is started and the left-side panel (dock) gets visible but with unreadable/corrupted launchers and comments.

Any window on the desktop leaves a white area when moved/closed. Those white areas can be fixed by adding "CLUTTER_VBLANK=none" too to the user's .profile.

Futhermore , there are other issues such as corruption och top-panel icons when eg pressing the ubuntu-logo, corrupted window shadows, poor refresh of the desktop panel/dock etc which I assume are side-effects too of the same problem.
