2x anti aliasing causes GUITextures to have banding issues?

Unity Engine

When I enable anti-aliasing (via Quality Settings) all GUITextures have a very noticeable “banding / dithering” effect on my iPad. The GUITextures look like they are being converter to 16 bit or something. When I turn off anti aliasing they look great.

Is this a known problem?

Thanks.

sigh, did you try to search forums for msaa banding?
in 3.4 added checkbox to force 32bit fb color, for now you can do it yourself in AppController.mm

sigh, I searched for anti aliasing banding it didn’t return anything. I’ve been an active member of the Unity forums since 2005 and know to search before asking. Thanks for your response.

“Use it only if you see banding, as it has performance implications” because of this message I didn’t tried it and decided to fight the banding by converting the GUITexture to 256 colors with noise which worked OK.
