Plaster in corners

[Styx]

I have leftover angles after laying the floor chipboard that are also enough for the inner corners. Maybe I should put them there then... and is it best to place them between gypsum and OSB in that case? There won't be a problem with the drywall screw gripping incorrectly causing a gap between the sheet metal and OSB?

We usually place them between the boards anyway, and I haven't experienced the screw not pulling properly. The actual angles are best screwed in with assembly screws so you don't have to worry about the screw bulging the drywall.

Thanks for the answer. I will test. If it doesn't work well, it's easy to remove
