It seems the problem might have something to do with how shadows are rendered, AFAIK using nouveau has disabled shadows (possibly due to lower performance of graphics card on nouveau) however the shadows are enabled using the proprietary Nvidia driver 361.42...
I'm just guessing the shadows are disabled as windows are not borderless even using default theme Ambiance/Radiance -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1576228 Title: Black borders around all windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1576228/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
