Binary package hint: compiz
I've just upgraded to ubuntu 11.04
in the previous version I've installed a color filter that made my standard window background color transparent, together with the blur plugin this gave my windows a nice glassy effect.
The color filter still works, however it acts strange. When I first activate the screen filtering everything is OK, then when I open another window it is not filtered. So if I press the shortcut key to activate screen filtering again, the new window becomes filtered, but the old ones are no longer filtered. And what makes the situation even worse is that after pressing the shortcut key several times, some of the windows (like geany or pidgin chat window) stops being refreshed. They still do their work only the changes on them are not drawn on the screen.
I have two monitors which I use as multiple X screens because I don't like Xinerama. I don't know if that makes a difference. Another change in compiz is that it doesn't start automatically for both screens, but if I start compiz only on one screen the color filter issue still exists.
My aplologies for the double post but I forgot to mention two things in my original post:
1) I've tried activating the "Copy to texture" plugin but it made no difference
2) I'm running compiz with emerald on ubuntu classic because at first start a window poped up saying that I don't have a good enough videocard to run unity, which is strange because I have a Raden HD 4500 with firegl and that should be enough - it is enough to rotate a transparent cube deformed to a sphere. But I was gonna switch to classic anyway.
