Public bug reported:
Binary package hint: xorg
With Gutsy (20070821.1) on an Acer Travelmate C104TCi (C100) there is
video corruption, window (areas) left unpainted, invalidated regions not
repainted, and more. All this causes interaction with dialogs and
windows to be hit-and-miss since often many components in the windows
aren't visible. It also appears to cause the PC to 'freeze' for 1/2
second or so, causing the mouse pointer to pause.
/var/log/Xorg.0.log shows large numbers of reports that seem to coincide
with the display faults:
