Subject: Where the black spots on my X windows come from?

Does anyone has the problem with X ?

There are black spots on my twm pop-up menu and on some of applications
such as gs (ghostscript) and xfig ( it is worst in xfig, it also has
lines too.)  It is regardless the background / foreground color 
of windows, they are always black.  It is also regardless which video
mode is on "640x480" or "1024x768".  When the pop-up window is gone,
the stain will be left on the other windows underneath it, but not the
portion was on the root window (namely the root window background is
always clean).  I can clean the stain left on the
other window by refreshing windows.  But I cannot clean the stains on
gs or xfig.   

When X is gone (by press <crtl><alt><backspace>, the console screen
has some stain (spots, short lines and funny characters) left, even
I went to vi screen they are still there.

Is it come from the video card?  No, I don't think so.  Because 
MS windows is o.k.  and also xterm and other games windows are o.k.
>From Xserver? 

Any glue? any way of fix?

 My 486 configuration is :
   NICE-EISA 486DX2-66MHZ with 256 cache, AMI BIOS
     16MB RAM
     Adatec 1542B SCSI Host Adapter
     Teac 1.2 MB 5.25" Floppy, Teac 1.4 MB 3.5" Diskette
     Toshiba 1.2 GB SCSI Hard disk
     Wangtek 5150ES 250 Mag Tape drive
     Diamond Stealth VRAM 1MB on board
     Viewsonic 7 17" FS Multi-Freq Color Monitor

  It is running SLS Linux version 0.99.p14-62 and X386.S3-0.3.1 xserver.
I use "s3 5 9 " to set the third dot clock. Then I just use "startx" to 
bring X up. And part of my Xconfig is as follow:

vga256
  Virtual       1024 768
  Clocks        25 28 75
  ViewPort      0 0
  Modes         "640x480" "1024x768"
ModeDB
# name        clock   horizontal timing     vertical timing      flags
"640x480"     25     640  672  768  800    480  490  492  525
"1024x768"    75     1024 1048 1184 1328    768  771  777  806

Any help will be appreciated.
