Problem occurs when running the XF86_SVGA XServer (from either XFree86 or
downloaded from
ftp://ftp.diamondmm.com/pub/s3/desktop/395/395_xf86_1011.tar.gz), and
running Citrix Metaframe Client 3.00.97 connecting to a Windows NT4
machine, and running MS Outlook 97 or 98.

Clicking in Outlook message header pane scroll bar, to page down, will
reliably cause the XServer to draw pseudo-random XOR rectangles on the
screen, will cause X to use all available CPU, and will cause machine to be
inoperable. Console won't respond to anything, including Ctrl-Alt-Del,
Ctrl-Alt-Fn and Ctrl-Alt-[+|-|Bkspce] Only solution is to remotely log in
and kill the X process.

Also, in normal case (prior to causing X to malfunction as above), pressing
Ctrl-Alt-Fn to get to Virtual Terminal n while X is running will often
cause X to lock up. Screen re-syncs, but no virtual terminal is visible. X
remains on screen, but doesn't respond to mouse or keyboard. Again, only
solution is to remotely log in and kill X.

These happen regardless of whether the BIOS upgrade
(ftp://ftp.diamondmm.com/pub/s3/desktop/395/395_bios_2129.exe) has been
installed.

XServer startup:
