i have recently been developing application in linux, specifically a
imageviewer application, and since all i had to do was blit a 2d
image to the screen i programmed it entirely in xlib using the dbe
and mit-shm extension. it works very well. Now the reason for this
app was in a rendering cluster, machines(including the same one as
the displaying machine) would volume render a piece of the total
image and send it on to the machine that was the display. The
rendering code utilizes opengl and glx. Now if I run the display on
a different machine without a rendering code running, the imageviewer
app works very well. The problems comes about when I have an
instance of the rendering code up, my imageviewer app is no longer
double buffered, but appears to be copied into the frame buffer. I
have tried many ideas to correct this, as I thought that maybe the
rendering code was using to much card memory and booting imageviewer
out of the card. Now I did not write the rendering code, but the
developer insists that he is reducing the memory footprint of this
app, but the problem persists. I would very much like to hear any
suggestions or insight into my problem, as like I said, I am only a
budding x developer, first got my feet wet just 1 1/2 months ago.
Thanks in advance.
Do any of your image viewer's calls to Xdbe* functions return an
error? If so, which one(s)?

no i do not believe any errors are returned, i have not changed the
default handler for regular errors, as i figured it would show them in
the xterm window if they occurred. i will update the code to list
regular errors in the log file and see if any show up, but no, i do not
see any errors occuring in the dbe code. I would say no errors are
returning, will reply again if i see something in the log file.
