The NetBSD Foundation, Inc.
System: NetBSD 8.99.1 NetBSD 8.99.1 (NIGHT-OWL) #535: Fri Aug 25 17:24:53 CEST 2017 amd64
Architecture: x86_64
Machine: amd64

When using a window manage with compositing, e.g. XFce4 in the default
setup, there are visible artefacts and (in the order of seconds) delayed
redraws of screen parts during every day use. Worse: when running something
that scrolls quickly (like rxvt and an ssh session to a "remote" machine
which runs "cvs up" on an ssd) the display sometimes "freezes". That is:
mouse pointer still moves, but window manager is blocked, all window contents
are frozen.

Switching VTs works, shutting down works cleanly as well.

I am not sure what process I should attach gdb to, any hints welcome.
