Yes, it sounds like your fill valve is sticking. Opening the tub faucet
probably drops the pressure just enough to allow it to open. In addition to
replacing the fill valve, you might want to make sure you pressure is below
80 psi.

I have a problem with my traditional toilet in the basement bathroom.
Occasionally the tank won't refill with water after the toilet is
flushed, however, if I turn on the water in the bathtub beside it the
tank will refill after a few seconds. What causes this problem?
Thanks.
