Description of the Issue

The image is dark, brightness and or contrast are off. It looks the image as a whole is dimmed but certain parts seem to have correct brightness values (see screenshots below). In some games, liek Crazy Taxi, issue appears always. In some others, like Dead or Alive, the brightness is correct while the camera rotates and zooms before starting a fight but as soon as fight starts the issue appears. This happens in both master r8.1 and beta releases. I have tried r7 but I was not able to select the bios and games folders so I was not able to load a game to check if issue is still there. This problem does not appear in the libretro core (see screenshot below)

Debugging Steps Tested

  • Tested several beta releases from master and fh branches. All have same issues.
  • Tried to change cable type and region settings in options but no difference.
  • Tried both synchronous rendering ON/OFF but no difference
  • Tried to switch to 640x480 but this option does not have any effect on Nvidia Shield
