Currently, there are a couple of annoying bugs in the Ubuntu 12.04 Precise Pangolin Classic GNOME session when using Compiz:
- For some fullscreen windows such as Flashplayer (this doesn't happen for HTML5), the GNOME panels are displayed over the fullscreen window, like in the screenshot above;
- When a window is displayed on two virtual desktops, if the window loses focus, its position is randomly changed to somewhere on the first virtual desktop.
To fix these Compiz with Classic GNOME issues, WebUpd8 reader Alexis Lavie has created a PPA with a patch for Compiz (the patch itself is not his work).
Add the PPA and install the fixed Compiz for Classic GNOME session, use the commands below:
sudo add-apt-repository ppa:lavie-alexis/compiz-precise+placepluginfixed
sudo apt-get update
sudo apt-get upgrade
Once installed, log out and log back in.
Thanks to Alexis Lavie for the PPA and tip!
