every time when I use alpha in the viewport display I get weird pixels. It looks like it doesnt appear on simple scenes like a cube or sphere etc.
Could you guys please test it so I can see its either a blender problem or a problem with my hardware.
Version 2.90.0 works perfectly. It starts with 2.91.0 / 2.92.0 Alpha.
