some rooms in my house which I dry-walled 19 yrs ago are experiencing some sort of failure. the (paper) tape appears to have shrunk. it is showing cracks on the tape edges. I tried the cheap and dirty method of mudding the crack, prime, paint. of course they came back.

doe this mean cut it all out and re-tape? just a dyi'r so I just used the blue or green lid mud.

Paper tape does not shrink, any flaws should have shown up years ago.
More likely somethings moving.
Likely needed more screws added.
