Hi Pasha,

  turn on the backing store of the X server. For example on my Linux box
using Accellerated X I've to set in /etc/Xaccel.ini:

[SETTINGS]
    BackingStore = YES;
    SaveUnders = YES;

Each server has its own options, of course, and some vendors have it
enabled by default (e.g. HP-UX).

Cheers, Fons.
