Ubuntu – Dragging a window is laggy (windows do not follow the mouse while moving smoothly)


When trying to drag a window the whole screen becomes laggy and some windows when dragged do not even appear until I release the mouse. They do appear where the window was suppose to end up after the drag but the dragging animation that happens while dragging is not seen.

I am using a NVIDIA 9500 GT 1GB with the proprietary drivers, an Intel Core 2 Duo 8500 and 4GB RAM just to make sure that this is not the problem. In 11.04 it worked correctly when dragging.

  • Install CompizConfig Settings Manager:

    sudo apt-get install compizconfig-settings-manager

    And in Composite, disable Detect Refresh Rate and slide the Refresh Rate up to more than 70.

    Under Mouse Polling Position, change Mouse Poll Interval to 1.

    Disabling Plugin Grid also might help, but that disables window snapping!!
