Color reproduction seems "off" after update #62

Closed mcdax closed 5 months ago

mcdax commented 5 months ago

Since one of the recent updates (Arch, KDE Plasma 6.1.0, 6.9.5-arch1-1), I'm facing a major issue with my screen's color accuracy. The colors appear oversaturated, and it looks like there's a translucent white layer overlaying the screen. I've tried applying an ICC profile based on a review of the notebook, but it hasn’t helped in removing this "overlay".

The problem persists regardless of the brightness / backlight setting. The Night-life filter is disabled.

Has anyone else noticed a similar issue?

Does this happens even when the device is on charge or only on battery (if u are on charge make sure to disable the battery saver mode)

Wow, I have just plugged it in and it is much better now! Thanks!

But I do not find any config for that in the settings.

You can disable this for battery as well by running grubby --update-kernel DEFAULT --args "amdgpu.abmlevel=0" as root. This is caused by some amdgpu lcd power saving feature. In theory this was supposed to be fixed to not to enable it for oled displays. (see: https://gitlab.freedesktop.org/drm/amd/-/issues/3359)

After adding the Kernel parameter, everything is fine again. Thank you very much!
