Check the roof vent and make sure it is open.
I think this is your problem. Clogged vent, tank slowly builds slight pressure, flush toilet, pressure released.
Did either of you read the entire post? OP stated that he cleared the vent.
I will add did be clear the correct vent, but that seems to also answered in the posting as the water was putting in was coming out clean. His thought about the vent extending too far into the tank has some credence.
Not sure how the poo pyramid would cause the toilet to burp, but have not had that experance.
