This PR fixes an issue with the NVIDIA 3000/4000 series cards. The cause might be that when blending is turned off and the fragment output has an alpha of 0.0 the fragment might be discarded. This is a guess of course. By setting the Alpha to 1.0 for scopes and enabling alpha blending when drawing the meta data text seems to fix the issue.
