Beryl was just amazing on Ubuntu 7.04... until you had to work at the same time it was running (at least with an nVidia graphic card). Now that Beryl and Compiz stand united under the Compiz fusion flag, I must say it has become more than just usable! It is bloody stunning!

If you want to convince yourself just play the following video:

I can say now that I really can work while Compiz fusion is turned on.

Well, that was not supposed to be one more of those I love Compiz post... I just found a small workaround for a bug. Users might experience that some windows of specific applications cover suddenly their entire screen preventing access to the desktop's taskbar and the windows titlebar...

I just found that this was caused by a bug in the "Workarounds" plugin which enables correct handling of various special applications (Java- and Qt-based applications for example).

The solution is peculiar:

First, open the CompizConfig Settings Manager (You may have to install it first):

~$ ccsm

Just deactivate the "Legacy Fullscreen Support" in the "Workarounds" settings ("Utility" category). This will cause some Wine and some fullscreen applications (Like the EVE Online client) to display improperly, but we'll reactivate it in the end.

Open all the applications which suffered the display default. They should open normally.

Reactivate the "Legacy Fullscreen Support" option.

Test whether the applications which did not behave still open normally.

Et voilà!
