glBlitFramebuffer from FBO -> Back Buffer leaves trails on Nexus 10

I reported this a while back against Android 4.3 on the old forums but since you guys blew away all the old content I'm reporting it again. I just updated my Nexus 10 to KitKat hoping the problem might be fixed but it's still there.

This was the old thread: http://forums.arm.com/index.php?/topic/17088-msaa-renderbuffer-back-buffer-blit-generates-invalid-operation-error-on-nexus-10/

Basically we're rendering off-screen to an FBO with an RGBA texture attached to COLOR_ATTACHMENT0. At the end of the frame we try to blit this image to the back buffer using glBlitFramebuffer. What we get in the back buffer is a trail of all previous frames as though we were never clearing the screen between frames. If I draw the image to the back buffer as a textured quad instead of using BlitFramebuffer then it looks correct, so I don't think it's really an issue in the source image (not to mention this code works fine on Desktop GL and other non-Mali ES 3.0 devices).

Here's a link to an APK file that shows the problem. Just load any of the sample documents and try to manipulate the camera and you'll see the trails.
