Oops! Sorry for the mis quote,
The command all on one line does not help, in fact if your quick enough on the button, only Y will move...
So short answer is no, not any less buggy... or at least still buggy.

Very odd.
If you Halscope the two jog pins, do you see any offset?
JT (on iRC) wondered if the axis accelerations were the same.
I can imagine connecting the jog button to some random HAL function (like an "or2") just to buffer it in HAL.
I think there are some slight velocity profiling differences between the "main" and "secondary" axes. Specifically I don't think that the overall max velocity applies to the secondaries. (it is very debatable whether it should apply to the primaries). You could try setting the [TRAJ] MAX_VELOCITY and MAX_ACCELERATION well out of the way of the individual [AXIS_N] MAX_VELOCITY and MAX_ACCELERATION

all accel's are the same.
New question related, what is
•halui.mode.is-teleop (bit, out) - pin showing coordinated jog mode is on
coordinated jog mode? could this be the answer?

If the short button press pulse turns out to be the problem you could consider using a "oneshot" component and set it's output to a minimum length that works for the jog.
So you could try sending the button press to the input of a oneshot and the output of the oneshot to the halui.jogs

Just a short quiz...
Are you running gantrykins?
After you home all 4 axis and switch to world mode does the gantry jog properly with the keyboard up/down arrow keys?
When you open up the Show Hal Configuration window and put
axis.0.motor-pos-cmd
axis.1.motor-pos-cmd
axis.2.motor-pos-cmd
axis.3.motor-pos-cmd
in the Watch window does axis 1 and 3 move the same amount when your in World Mode and using the keyboard?
