Black bars instead of drop shadow

[zoho]

Hello:

I am running compiz from sid on debian and everything is wroking, as far as I can tell, except for drop shadows. I am attaching a screenshot to illustrate the problem. Does anyone have ideas on what might be causing the problem?

here is my video section of my xorg.conf

Section "Device"
Identifier "ATI Radeon 9250"
BusID "PCI:1:8:0"
Driver "radeon"
Option "AccelMethod" "EXA"
Option "ColorTiling" "true"
Option "DDCMode" "true"
Option "EnablePageFlip" "true"
Option "EXANoOffscreenPixmaps" "true"
Option "GARTSize" "64"
EndSection

I am using a radeon PCI 9250 graphics card on a PPC. Thank you for any suggestions!

Does it happen if you use emerald? If not, this is probably the same as this bug: https://bugs.freedesktop.org/show_bug.cgi?id=11268

Debian sid does not package emerald as far as I can tell so I have no way to try it unless I complie from source :(

What version of xorg do you have installed?

Well that means it' sdefinitely not the same bug as what I linked to...

Try this... Start up ccsm, go into the window decoration plugin, and set the "Shadow windows" line to "!any", and see if that makes the black bars go away.

That's clearly not a solution, but it's at least a work around (assuming it works).

unfortunately changing "any" to "!any" in ccsm -> window decoration -> shadow windows had no effect.

After playing with my xorg.conf and switching the AccelMethod to XAA as well as setting XAANoOffscreenPixmaps, the black boarders went away however everything is dog slow. I have switched back to EXA and everything is fine and normal speed except that the bars are back.

I guess we can narrow down the culprits :D

After reporting this bug to the Debian Bug Tracking System I was given the advice to try adding "EXANoCompsite" to my xorg.conf.

It works !
