I have recently installed GNOME 3 on my Ubuntu 12.04 and it seems that most of its fancy effects work pretty smoothly. Strangely though, dragging a window is slow and glitchy. Is it caused by some effect which can be disabled?

    @j0k [sf]? I think you mean [su]. Or [ubuntu.se] perhaps. – Michael Hampton Feb 05 '13 at 18:38

Slow glitchy window movement used to be a problem with the open source ATI drivers. As GNOME3 now uses OpenGL pretty heavily, do you have the most recent drivers for your graphics card and have you tried with the closed source ones if they are available?

Assuming you are using compiz for the "fancy effects", open a terminal and type ccsm and then play with the settings there. Try disabling the ones involving window effects.
