Have you tried running the Xf4vnc framebuffer server together with the
fbvnc client for the local display? That's what I'm using in the chroot
debian environment. I never tried native X11 on current models, so I
can't comment on that.

This is strange, my guess would be that there's a separate process that
also reads from the touchscreen and the resulting race condition breaks
the protocol.

Or does the native X use something other than the default touchscreen
device interface to read that's timing sensitive? Last time I looked
there was no source available for tha pdaXrom X server unfortunately.
