Helped out marshalling at the kids sponsored ride and took my mtb.. A Spesh butcher on the front and maxis ardent on the back, both Tubeless, low psi.
Havent ridden a mtb on the road for a few years (usually ride a tripster with 28c contis on the road) but whilst riding it just wouldnt hold a straight line.. dint remember drinking that morning ..... but literally making constant adjustment to steer straight...

Normal? Or are have my riding skills gone from mincing to appallingly shite?

Unless your tyres were literally flat that's a bit odd. I do find it harder to ride my MTB no handed than my road bike though.

You are the driver in almost any black & white movie

I had a similar problem, my wheels weren't centred/ dished correctly.
Low pressure can't help though.

Depends on how the tyre tracks as well. Or if your headset is buggered/too tight.

Really? I find my MTB much more stable.

Wasn't there a thread a couple of weeks ago where someone was having similar troubles all the time on a fatbike and was going to get rid, but was advised to switch tyres and it fixed it straight away. Can't find the thread though.

Headset a bit tight?

Could have been the headset thinking about it as i gave it a quick tightening as i thought it seemed a bit loose when i put a new gear cable on (i could spin the spacers and bearing cap cover with my thumb)..
Only gave it 1/4 of a turn though. Was in a bit of a rush though..

*Heads off to find torque wrench and look up bearing torque settings

Are the tyres seated correctly on the rims?
Has the tyre sidewall started to split form the bead? (I've had that happen once with a non-TR Ardent whilst running tubeless).

A tight or brindled headset bearing will make a bike veer off sideways.

Head angle effects the none handed thing particularly at low speeds. I find steeper head angle XC bikes 'track' a lot straigher than a slack trail bike. My 29er with the 51mm offset fork and a little longer travel than stock is bad when on slow climbs but is brilliant at speed.

My road bike's headset got a bit "indexed" after being left a few months (I assume that's what brindled is) and was just off-centre

It was easily rideable but definitely weird

Are they ok with a higher pressure? Then if so the simple solution might be to add more air for the road and let it out for off-road stuff.
