[00:06] <andoma> I've seen some problems which may or may not be related to Compiz, i'm not sure. When running an OpenGL application (anyone will do, glxgears for example) with nvidias proprietary drivers there seem to be a freeze of display updates (sometimes up to half a second) when changing focus between windows 
[00:06] <andoma> Seen on ubuntu 16.04 (both with unity session and with Gnome flashback compiz-session)
