Retina MBP screen is black when switching spaces

[Jacobwilson99]

When I switch between spaces, the screen flashes black and then loads the wallpaper and mounted drives and such.

When I scale the screen to 1920x1200, and switch spaces, only the part of the screen that would be "Best for Retina" blinks black. The rest of the screen displays wonderfully. It has a Samsung screen, btw.

This never happened on my 2007 MBP.

Any help?

When you scale up to 1920x1200 on the retina model, the os is actually rendering at 3840x2400 then scaling back down to 2880x1800 and it's why it looks so good even though it's scaled. Now multiply that by multiple spaces. That is a lot of pixels to keep in the framebuffer at one time.

It wouldn't surprise me if some kind of a buffer flush or reset happens when switching spaces.

Then, hypothetically, if I ran the screen at the native resolution, there wouldn't be any blackout?

I was just throwing out a theory. Played with a coworker's rMBP yesterday and didn't this happen.

Anyone else have any ideas?
