Bug ID: 112148
Summary: Broken colors on RX 5700 with adjusted brightness
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: not set
Priority: not set
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: mlichvar@redhat.com
I have an RX 5700 card connected to a monitor which doesn't display dark colors
very well. The brightness needs to be adjusted in software. I use the xcalib
tool like this:
xcalib -c
xcalib -a -b 10 -co 90
This displays dark colors well, but some images/videos have weird artifacts.
After playing with a color picker it looks like colors that have the green
component zero are much brighter than they should be. For example, color
#750000 is much brighter than #750100. I'll attach some images that show the
problem.
When the monitor is connected to a different computer (with a non-AMD GPU)
configured with the same xcalib commands, the problem disappears, so it seems
to be specific to the hardware/driver.
Please let me know if you need more information.
Installed packages:
kernel-5.3.6-300.fc31.x86_64
xorg-x11-server-Xorg-1.20.5-7.fc31.x86_64
xorg-x11-drv-amdgpu-19.1.0-1.fc31.x86_64
mesa-dri-drivers-19.2.0-1.fc31.x86_64
xcalib-0.8-24.fc31.x86_64
