Skybox problem on iPad

My game uses floating GUI windows that sometimes get moved out of the way to reveal the skybox below.

When there was no skybox, just a background color, everything worked fine. But now that I’ve added the skybox, it’s not being drawn, instead multiple copies of my window are being drawn. Sort of like what happened in Windows XP when you had a crappy graphics card.

It works perfectly on the desktop, the problem only appears on the iPad.

Maybe this will help. Go to your Main Camera, check “Clear Flags” if you choose Don’t Clear, then it will be multiple copies just like you said.

Thanks, but that’s the first thing I checked. It’s set to Skybox.

I’ve tried both attaching the Skybox to the camera and assigning it in render settings. Neither works on the iPad (though both work on the desktop).
