Summary 08621: Bgfx randomly ignores Brightness/Contrast/Gamma values when entering/exiting full screen
Description Sometimes, when using bgfx with any backend, the previously adjusted values for Brightness, Contrast or Gamma won't be reflected on screen.
Steps To Reproduce -Set video to bgfx, any backend (for example, opengl).
-Load nes smb.
-Modify the Brightness/Contrast/Gamma sliders.
-Press Alt+Enter to enter/leave full screen mode, the screen will be randomly displayed with or without the specified values.

Alternatively, if the screen is currently displaying the correct values, changing between different Screen Effects can also deactivate/reactivate them at random.
