>Description:
When using X11 forwarding, GL applications crash (all from MesaDemos that
I tried, e.g. gearbox).
Locally they seem to work. Remotely forwarded from a slow
machine to a faster seems to work, too, but the sample is
not statistically significant.
I've tracked down the crash location to this(gdb) up

/usr/pkg/share/examples/MesaDemos/demos/gearbox
>How-To-Repeat:
>Fix:
workaround: Don't use MesaLib remotely; e.g. install
xlockmore-lite to prevent it to crash when a GL mode is chosen,
or force it to a safe mode (like "blank").
