My experience is that subtle bugs with pointer grabbing cannot be
reproduced in Xephyr (or any environment you specifically set up for
debugging) at all, but it can't hurt to try.

You could try adding a new master pointer and attaching the device you
want to behave separately to it.

The disadvantage is that 99% of window managers have no proper support
for multi-pointer X environments, and either crash or freeze.

I think mpwm is the only window manager that will work, but it will take
a lot of time to find a recent copy.
