Mine did this, jumping back to the center when pushed to one end ( scene A side for me).
I took the crossfader out and on each end there is a screw that sets the end stop. I adjusted the corresponding screw in a touch and put it all back together.
It’s been perfect ever since.
You can see the small black slotted head screw in the image neilbaldwin posted on that eu thread.
I don’t recommend doing this if you’re OT is still under warranty, or if you’re not happy with fixing electronics/computers etc.
Having said that, it’s really not difficult, if you can fit a graphics card you should be fine. This biggest issue is that there isn’t much spare length on the ribbon cables that connect the control surface to the main board, so be careful when you lift it off…
