Fix flickering when switching display power modes

So far we've been Waiting for the next frame but it doesn't
mean that it will be visible on the screen.

We're usually rendering with 2 buffers and it's possible that
we'll switch the display power mode before anything has hit
the display.

Increased the timeout for now until we have a better alternative.
