bug with beryl / xfce

I am not sure if this is a granular problem or general xfce but it seems if i enable the desktop effects (i have an nvidia card) and disable the effects the toolbar with the min and max buttons disappears and all the panels mount to the top left of the screen and can't be moved. The only way around it is to reenable the desktop effects again.

Another problem i had using berly was that suddenly the desktop icons disappeared and all the windows I were using were gone (although still running). FLicking between the window managers in the beryl manager brought them back but beryl became unusable and I again had the toolbar issue on the xfce desktop. I am running compiz now instead and it seems much more stable but if i turn off the 3d effects all together xfce is not usable anymore.

This is a known issue. With 3D effects enabled on certain graphic cards, the window borders disappear.

To try to correct this problem, add these lines in the Device section in the /etc/X11/xorg.conf file (if these are not already present):
    Option         "AllowGLXWithComposite"
    Option         "XAANoOffscreenPixmaps"
    Option         "AddARGBGLXVisuals" "True"

I added those lines and things seem a bit more stable now.

if i switch back to a non 3d desktop and use xfce as the window manager the toolbars are still gone though. think this might be an xfce bug because the same happens on my laptop running xubuntu.
