minimize plugin modifying opacity attribute like that is wrong. fade
plugin should be modified if you want to disable fading when windows are
minimized.

Adding a call to damageScreen like that is also wrong. That it prevents
tearing for you doesn't justify it. I assume that it prevents tearing
because your driver doesn't support GLX_SGI_video_sync, which allow
compiz to synchronize partial buffer swaps to the vblank. You can't
replace efficient redrawing of part of the screen with fullscreen
redrawing to workaround missing features a specific OpenGL
implementation.
