Welp, I had this very same issue today. All the drains started to back up, 3 toilets, 3 shower drains, and it happen right after the drain cycle of the clothes washer. I went thru all the basic things, checked each area individually, tried liquid plumr, and then read this forum. I have a ton of trees on the property but the city just changed my sewer line when moving their wye in the line.
Long story short, I jumped on the roof with a shopvac and suctioned out the vent pipes and BOOM....clean and clear. All the drains are clear and flowing easy.
Not sure that this is your problem, but it was ALOT cheaper than paying a plumber. I did have to sanitize the pour shopvac thou!! haha
