[Problem]
Artifacts with cairo dock 2.0 due perhaps to error in 'GL_EXT_texture_from_pixmap' in OpenGL.

[Original Description]
When using the latest version of cairo dock 2.0 , on hover over the dock the background becomes black.

Even in normal state the transparency is not perfect.

Attaching a screenshot of the problem.
screenshot legend:
1: as soon as the dock starts , not fully transparent[ the icons dont appear and the logo from the nearby panel is retained!]
2: on hover the dock background turns black
3: even on release of hover the dock has the black background , and at random returns to state 1 , where the icons disappear and the logo from the nearby panel is retained

The only solution is to not use the openGL version and to run caio-dock as[non-openGL] :
$cairo-dock -c
