When running the vulkan backend on the mac the swapchain images are not of the correct size, copying offscreen textures to the swapchain generates distorted screens.

Issue seems that GHOST_ContextVK doesn't take the monitor DPI into account. See WM_window_set_dpi where there are some notes about its resolution. Might be that we need to tweak the metal layer as well.

Accoriding to MoltenVK we need to set self.view.contentScaleFactor = UIScreen.mainScreen.nativeScale; before requesting the surface capabilities. https://github.com/KhronosGroup/MoltenVK/issues/428#issuecomment-450687675

In blender the native scale is already stored inside m_nativePixelSize but not inside the view.
