I have the same difficulty. Our configurations are similar.

In an xterm, scrolling or horizontal dragging caused the horizontal
chips to pop up. I was using a clone Tseng labs et4000 card.

I do NOT have this problem with an ancient Paradise 512k vga card, but
I can only run mono mode with it , as it does not support 256 colors.
A STB Powergraph X-24 is on order, which uses the s3 chipset. I am hoping it
will be ok.

Software:
   XFree 1.3, Linux kernel 0.99.pl12alpha

Hardware:
    Soundblaster IRQ 7.
    Com ports.
     14,400 v.42 bis modem with AT&T chipset (COM3).
   IDE controller - 130 MB Seagate (DOS), 340MB Maxtor (DOS+Linux)
   Microsoft bus mouse (IRQ 5).

CPU: AMD 386/40, 8 megs assorted SIMMs,

Under DOS, I should also note that the tseng et4000 acted very odd, messing
up graphics on various video games unless I changed TURBO or the cacheing
parameters.

This was an ISA card.

So you are not the only one with this problem --- I posted a week ago and
didnt really get any answer, though someone did recommend the s3 chip cards.
