In the following single-headed setup GNU Emacs behaves as intended:

  Screen 0: minimum 320 x 200, current 1024 x 600, maximum 4096 x 4096
  VGA1 connected primary (normal left inverted right x axis y axis)
     1280x720      59.86 +
     1024x768      75.08    70.07    60.00
     832x624       74.55
     800x600       72.19    75.00    60.32    56.25
     640x480       75.00    72.81    66.67    60.00
     720x400       70.08
  LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y
axis) 228mm x 131mm
     1024x600      59.99*+
     800x600       60.32    56.25
     640x480       59.94

In this setup, as you can see, only the LVDS1 output is enabled.

However in my usual setup I have both outputs enabled for a dual-headed
display:

  Screen 0: minimum 320 x 200, current 2304 x 720, maximum 4096 x 4096
  VGA1 connected primary 1280x720+0+0 (normal left inverted right x axis
y axis) 340mm x 270mm
     1280x720      59.86*+
     1024x768      75.08    70.07    60.00
     832x624       74.55
     800x600       72.19    75.00    60.32    56.25
     640x480       75.00    72.81    66.67    60.00
     720x400       70.08
  LVDS1 connected 1024x600+1280+120 (normal left inverted right x axis y
axis) 228mm x 131mm
     1024x600      59.99*+
     800x600       60.32    56.25
     640x480       59.94

In this setup GNU Emacs corrupts the mode-line (a graphical glitch)
drawing over it the buffer's line that would otherwise be below it.

Refreshing the window with 'xrefresh' or just switching to another
window and back again repaints the mode-line content, so it looks
normal, until the next buffer scroll operation, when it gets corrupt
again.

Starting Emacs with the '-Q' option, without changing the frame's
geometry, and typing 'C-x d /dev <RET>' is sufficient to reproduce the
bug.  Actually, most of the time, Emacs windows that hold text
underneath the mode-line trigger the problem.

See the attached screenshot for how the corrupted mode-line looks like.
