            Bug ID: 109232
           Summary: Raven Ridge with ABM enabled turns display off
                    erroneously on mostly black colored windows
           Product: DRI
           Version: XOrg git
          Hardware: Other

          Priority: medium

xorg log

With ABM off and brightness at the minimum (0), the screen is on but low
brightness. If you set ABM to 4 and then maximize a black terminal window, the
screen will for all intents and purposes turn itself off. When going back to a
bright screen it will turn on again. By on and off here I don't mean actually
off, but the brightness is almost not visible.

I am using a Lenovo A485

I logged the actual and brightness settings with 1 second delay:

actual: 771 brightness: 0  abm level: 0 
actual: 771 brightness: 0  abm level: 0 
actual: 771 brightness: 0  abm level: 0 
actual: 771 brightness: 0  abm level: 0

ABM is turned to 4

/* Screen is on initially, but */
actual: 593 brightness: 0  abm level: 4 
actual: 428 brightness: 0  abm level: 4
/* About here the screen is basically off */
actual: 368 brightness: 0  abm level: 4
actual: 339 brightness: 0  abm level: 4
