Description

I'm using amd-staging-drm-next c55469bdd90b83bd31b40dd1eca5e50678731ac1 on

43:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Vega 10 XT [Radeon RX Vega 64] [1002:687f] (rev c1)

I have three AOC 1080p monitors connected over DP; xrandr gives

Screen 0: minimum 320 x 200, current 5760 x 1080, maximum 8192 x 8192
XWAYLAND0 connected 1920x1080+3840+0 (normal left inverted right x axis y axis) 600mm x 340mm
1920x1080 59.96+
XWAYLAND1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 600mm x 340mm
1920x1080 59.96+
XWAYLAND2 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 600mm x 340mm
1920x1080 59.96*+

Night Light in GNOME is applied only to the leftmost monitor, and if I do a VT switch, then it's only applied to the one in the middle.

This used to work correctly months ago.
