Set the correct contentsScale in the CALayer instead of using the default (1.0) which causes rendering artefacts in retina displays due to using a smaller bitamp than the display size. See: https://developer.apple.com/documentation/quartzcore/calayer/1410746-contentsscale?language=objc Fix: #3942 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7828>
