Ok, cool. Interesting then that show-fps 1 causes fluxus to be
aborted, but 2 (and perhaps others; untested) causes x to crash and
loop...

Just dirty standard built in card. This feels to me also the most
likely cause of the problem somehow.
lspci returns the following:
Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated
Graphics Controller (rev 03)

Thank you, I have built from that source now. No change - show-fps
still causes the Abort.

Not sure what instructions I was following. Bits from the website and
elsewhere as I was tweaking the RacketCollects= and also using
ODE_DOUBLE=1.
I originally built fluxus many months ago, and that was when I built a
lot of it's requirements from source (PLT 4.2.2 and Racket 5.1.1) -
thus I haven't changed any of that stuff...

Thank you for the info.

No worries. We'll see what happens just.

As mentioned above, the git repo build didn't help the issue...
I quickly skimmed the src and found show-fps calls SetFPSDisplay, but
couldn't find where the function originates.
Just me poking around not really knowing what I am looking for.
Any ideas where to go from here?
All the best,
