Turn off triangular hidden panel icon in full screen?

[NN635770105360640215UL]

When in full screen mode there are two triangle icons, left and bottom, there I think to remind you that there are hidden panels that will pop up if you move your mouse to those edges. (Strangely, there is no triangle at the top, despite having similar hidden features).

I find the triangles, bright white and intruding into the picture area, ugly, distracting and annoying, competing with the photograph for attention. I would love to turn them off. Is there a way?

If you press Cmd+T once you are in full screen, the Tools panel will appear, press it again and it will go and the triangle will go too. Cmd+B on the other side for the browser.

Ahhh! Totally non-intuitive but it works--thanks!
