A small question here for the forum expertise. How do you handle the installation of drywall on walls that bulge inward into the room, where there is a 6-7 mm gap at the top and bottom using a level? It's not visible when you look at the wall from the front, but it's more of a hassle if you later want to install moldings, a wall-mounted TV bench, etc., which will then tilt significantly or create quite ugly gaps to fill.
Do you try to even this out with some form of horizontal shim behind, e.g., 2 pieces of masonite strips on top of each other (OSB behind) or just put up the drywall as it is and solve the problem in the future?

I would not experiment with wedges behind the plaster as I would be more afraid of cracking it.
I wouldn't care and would solve any problems that arose later. It might not even be a problem later so don't worry about it now. A few mm here or there wouldn't matter to me.

Might be wise, as you say. However, it is hard gypsum that can withstand much more than regular drywall. I've leveled it with masonite around small reveals, but an entire wall is a different matter. It concerns only one wall where one might consider a future wall-mounted TV bench.Dr Benz said:
OSB + hard plasterboard. So studs and OSB are bulging.
Ah ok.
But the essence remains the same. You want the drywall as flat as possible against the substrate behind. In this case, OSB. Shimming it to make the wall appear straight, I would argue, is an enormous amount of work for what you get. It will create voids, and you can bet that the day you want to hang something, there's air behind, and you risk cracking the drywall instead.
