Toilet bowl overflowing by itself
the works in the tank do bubble a tiny amount but overnight the water level rises to the top and even flows over. If I flush it the water rushs out fine, looks normal. A day later it is full again.

Not suppost to bubble.
Got a picture taken looking down into the tank?
If there's water leaking from the tank to the bowl you need a new flapper.
If the float is stick and causing water to not shut off and leaking by you need a new fluid master ball cock.
Less then a $20.00 fix.

It is almost impossible for the toilet bowl to flush normally but overflow due to a slow leak through the tank flapper. You may need to have the bowl snaked to be sure there are not some obstruction (possibly many feet further down the drain pipe) that settles in place but is pushed out of the way with a fast inrush into the bowl during a normal flush. Also the venting for the drain pipe system needs to be checked for obstructions such as a birds nest or dry leaves.
