ᐅ Second layer of drywall on window reveal

Hello,
how should the second layer of drywall be installed around window reveals and patio door reveals? For the first layer, I simply butted the edges together. Should I do the same for the second visible layer, or should the edges be cut at an angle and then jointed? For the windows, I still have leftover pieces that cover the full height, but not for the patio doors.

Does anyone have experience with plastic drywall trim profiles that snap onto the drywall and connect to the window frame? Are these recommended?

Best regards,
Jens

There are drywall profiles that resemble plaster stop beads. This way, you can avoid adding an acrylic sealant joint afterward. But why a second layer? When we did it, we only installed one layer on the reveals. A reveal might be about 15cm (6 inches) wide, and one layer is more than stable enough.

One layer is not sufficient to bridge the gap between the window frame and the wooden stud frame; it needs to be double.
