Make sure to run the debugger with
run --GNU-Debug=XSynchronize
when debugging X11 errors.

I made a rather far fetching change last night to the XWindowBuffer
class, so my first thought is that this change may have triggered your
problem. I left the old code in place and you could test whether my
change caused this by changing the line
#if 0
into
#if 1
If this wasn't the source of the problem then we need to dig deeper.
The
first thing to do is to run the application with a debugger attached
and
set a break point into XGErrorHandler and report the backtraces you
get
from it. That will help us to pin down, which operations are causing
the
messages.
It would also be great to report any other log messages you get while
running the application.
Thank you for your help in tracking this down

I'm using the cairo backend (but I get others messages with art) on
Ubuntu 8.10. You will find attached the ouput of xdpyinfo. Are these
messages expected ? Can I do something about it ?
