Screwing those MDF boards into the studs, pulled the drywall full into the stud, removing a small gap and popping the drywall screws. It happens all the time in areas where drywall is not installed fully flush with the wall studs.

You could try taking a 1x4 or 2x4 block bigger than the bulge and hitting that with a hammer to repeat the gypsum. If it was put up with nails you might be good to go. If screwed you'll have to tighten the screw then spackle or mud it.

Gotcha! Not something I had ever bumped into. I appreciate the help! Do you think putting a few screws through the bulge would help? Or how would you recommend fixing?

Thanks for the help. That makes sense! I'll give it a few hits and see what happens! I'm guessing it's screwed, so I'll probably need to screw the gyp back down, right?

It almost looks like someone drywalled over electrical boxes.

Laundry room? My immediate thought was wet area + MDF = warping/swelling/etc. But Pioneer’s answer seems better informed.

/u/PioneerStandard's answer is partially correct, but not fully correct. While these bulges do occur because the drywall is not fully flush to the support behind it, bulges this big are usually because of either a foreign object (insulation, staple, etc.) rather than a drywall screw not fully seated. This also often occurs when the top plates sit back a bit from the studs.

A proper fix is to cut out the bulged area, remove all the loose material and mud over it. Answers that suggest hitting the area with a block/hammer, while may appear to work, only serve to break up the gypsum between the layers of paper. It may work, but it's not an actual fix.

No. The bulge is a broken patch of drywall. Put new screws below it into the studs on a non fucked area of drywall as 2 inches for the edge of the bulge. And cut the bulge out. Then patch the hole with a piece of drywall, mud, and drywall tape.

Vent pipie coupling. In the first picture. You screwed into it.
