* Legacy bug, very visible. * Suggest to fix this for user experience

Milan, this seems like a gfx issue. Can you take a look?

Looks like a gfx issue with low-res tiles...

I'm assuming at related and possibly the same as bug 1113435.

There's a backout of culling on inbound, can we verify if that fixes this issue once it hits central? If it is fixed then we should dupe this against bug 1113435.

This appears to be fixed
