screen updates one step behind user input on DisplayLink monitor

[mab]

When using the modesetting driver, screen updates on the monitor connected to the DisplayLink adapter stay one step behind user input. For example, if I type a letter, it's not shown on the screen until I type a second letter or nudge the mouse.

Ubuntu recently made modesetting the default driver (without xorg.conf), so it took me a while to figure what changed to cause this problem, which I didn't have with earlier Ubuntu releases. The problem doesn't occur with the Intel driver, which I can force with this xorg.conf file:

Section "Device"
        Identifier "Intel"                                                                                                                  
        Driver "intel"                                                                                                                      
EndSection

Does anybody know what's going on or what to do about it?
