[comp.sys.ibm.pc.hardware] problem with Gateway 2000 monitor at 1024x768 mode

I have this problem with my Gateway 2000 monitor when running Windows at
1024x768 mode. When I overlap two windows, the overlapped areas becomes
either darker or lighter than their default colors. Here's a graphical
representation of the problem:

I first thought it was a problem with the monitor, but the replacement gave
me the same result. Gateway's technician argued that it was due to the
fact that my monitor is interlaced at 1024x768 and further stressed that
other interlaced monitors have the same effect.(so, unless I got a non-intelacedmonitor, the problem can't be not fixed). But I don't believe this.

Is there any of you having the same problem as mine? Is my monitor exhibiting
normal behavior? I would really appreciate your answers.

Anyways, here is the configuration I have:

386-25 with 4 meg, no co-processor
ATI wonder with 512K
Gateway Crystal Screen 1024 (actually, it's a Tatung 1498x).
windows 3.0
dos 4.01
ATI windows drivers 2.1&2.2
80Meg IDE
mouse, modem, no printer.

would the graphics card have anything to do with this?
