thxs for this Jim, this week I will give this a deeper look, also Freds
ideas are in process, as we had Qjackctl running for 16 days during the
process Fred we could verify it has no errors in it, and as we use XFCE
on the DJ Touchscreens and Gnome on Digital Soundprocessing (both
Debian) and both stations give this effect with processing the VU
display I will start with the RTpriority of Jack, somehow this idea of
Fred seems to point in the right direction listening and seeing what
happens, followed by looking deeper into Xorg / Xrun

My thoughts would be to first try tweaking features/options for your
video card in xorg.conf. What kind of video card is in the computer?
Information can be gotten from:
# lspci
(from a shell prompt, and see what kind of video it has), but better
yet is to look at the output of " less /var/log/Xorg.0.log".
Note that once you figure out what Xorg video driver is being loaded,
you should be able to do:
# man <video driver>
Examples: man intel
man nouveau
man radeon
And get a list of options that you can use to try to get more stable
operation.
Finally, what OS version are you using, what version of Xorg, What
version of the Linux Kernel?
Also note that many video systems, such as ones that are/were
considered "high performance" tend to "wear out" (or wear out the
power supplies driving them) because they take lots of power, and make
lots of heat, so therefore are often short-lived.
PS: I have been running on a couple if different variations of Intel
integrated video system from the last few years just fine.
