I have a brand new Indigo 4000 Elan, running 4.0.5f and I am in the process of moving some code from a VGX to the Indigo.

I have a true color window with pixmode(PM_TTOB,1) and
                                rectzoom(4.0,4.0)

When I run this program, and do an lrectwrite to this window, I get a graphics error that wipes out the graphics server.  The SYSLOG reports:

	unix: WARNING: VDMA error : MC rev 1 (1) status 1
   	unix: WARNING: Gr2PixelDma graphics error
   	unix: WARNING: Graphics error: GE PC = 0x4045
	Xsession: shectman: fatal IO error 32 (Broken pipe)

The lrectwrite is writing a 128 x 128 truecolor array into a 512 x 512 window.
It is the rectzoom that is the cause of the problem.  If I comment out the
rectzoom the program does not trigger the graphics error.

If I run the same program on a VGX sending the graphics to my Indigo with
a rectzoom of 4x4, the program does not crash with an error.  On the other hand the rectzoom is not performed correctly either.  It appears more like a 2.5x4 zoom with the upper section of the window appearing as mostly black with an occasional random colored pixel thrown in.

Is this a known problem?  Are there any work-arounds other than not zooming?
