- I have run into a similar problem (resulting in "BadMatch" errors) on an
- AT&T X terminal. The problem traced back to a modification of the GC
- occurring before a draw, but not being forced to take effect (basically,
- an event queueing problem). Using an XSync( Display, False); prior to
- the draw fixed the problem.
