The Xorg xserver runs a scary amount of code in a signal handler.
It's supposed to make your mouse cursor move more smoothly, but I
can't spot the difference when I disable that "feature". Instead,
this "feature" breaks certain multi-card setups and god knows what.
So we're considering switching this off by default. Before we do
that, we'd like to do some wider testing. If you're regularly sitting
behind an OpenBSD machine running X, can you add the following lines
to /etc/X11/xorg.conf (or create one with these lines):
Section "ServerFlags"
Option "UseSIGIO" "false"
EndSection
and restart X. Let me know if you observe any significant changes in
behaviour.
Thanks,
Mark
