X: piedock not transparent + other transparency problems

[fdelente]

Hello.

This is on an Intel GM965 video chipset.

I'm running sawfish as a window manager, but I tried with xfwm4 and I have the same problem: when I pop up piedock, it should show a wheel of icon on the root window, but instead they appear on a big black square; clearly a transparency problem (I have the same problem with lxpanel).

I looked into /var/log/Xorg.0.log, I have compositing, opengl, every acceleration possible activated.

I re-emerged every library linked into piedock (png, Xrender, Xext, etc.) and piedock itself but to no avail.

Does anybody have the same problem? Is it a library or a video driver problem?

Thanks for any hint.
