This also happened to me in the "Opacity, Brightness and Saturation adjustments" plugin, where it is even more annoying:
* Open the "Opacity, Brightness and Saturation adjustments" plugin, this puts you on the opacity tab * Go to "Window specific settings" and press "New" * _First_ adjust the "Window values" slider to something other than 0, or this will get nasty * Press the "+" Button next to the "Windows" field * Put anything in the "Type" dropdown and "Value" Field * Press "Add" * The edit window only gets the "Type" selection, not the content of the "Value" field, e.g. only "class=" instead of "class=Ccsm" * This often matches every window: "class=" matched every single window on my screen, including the GNOME panels. * The new settings are applied immediately. This means that if you haven't adjusted the "Window values" slider before, now every window has an opacity of 0%, so every window disappears and you're left with an empty desktop, wondering what just happened. Apart from fixing this bug, I think it might also be a good idea to have the "Window values" slider default to something other than zero, at least for opacity, so people won't have windows suddenly disappear on them. -- Grabbing of Window Classes doesn't work in 'Place windows - Fixed window placement' https://bugs.launchpad.net/bugs/584894 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
