I noticed on Fx 52 when I received a Facebook chat message (with no chat window open yet) the other day that gfxCardStatus would show me a switch between the integrated and the discrete graphics card of my 2013 MacBook Pro several times, before the chat window finally opens at the bottom of the FB page.

Not really a bug as everything works, but might be interesting to find out what causes Fx to switch the graphic cards so many times.

Creating a 2d canvas would probably do it, creating webgl canvas certainly would.

Does it happen with gfx.canvas.azure.accelerated set to false (restart required)?
