Xcode 10 gives screenshots in scaled resolution

Xcode 10 iOS simulator makes screenshots in scaled resolution, I cannot make him to produce screenshots in actual size. I work on 5K resolution iMac. Screenshots are twice smaller then they should be. For example, iPhone XR gives 1792 × 828. In Debug menu there is no "Optimize Rendering for Window Scale" option. "Debug"->"Physycal Size" or "Point/Pixel Accurate" makes no changes on screenshot resolution.
