Description guimarcalsilva 2020-11-18 03:07:08 UTC

SUMMARY


STEPS TO REPRODUCE
1. Open Krunner with alt+f2
2. Click settings

OBSERVED RESULT

List on the left of window is gray instead of white. If I click on the first item of the list it becomes white as expected. Please check video: 

EXPECTED RESULT

It should be white like all other lists. 

I'm using the latest unstable version of KDE Neon as of november 17.

Comment 2 guimarcalsilva 2020-11-18 03:11:00 UTC

I have just noticed the same thing is happening when clicking on "Devices" on Kinfocenter.

Comment 3 Nate Graham 2020-11-18 15:37:35 UTC

Can confirm, sometimes. It seems semi-random for me.

Comment 4 Nate Graham 2020-11-18 15:39:02 UTC

Can reproduce 100% by running `systemsettings5 formats`.

Oddly, `systemsettings5 kcm_colors` causes the list to have the wrong color for a moment, and then it switches to the correct one.

Couldn't it be caused by the code used to color the "tools area"? It's been a while since I last tested Neon unstable but I don't remember seeing this bug before the tools area patch.

[sidebar] Fix background colour of listview

Kirigami.Theme.colorSet was set, but it was also set to inherit from the
parent color set.

One exists somewhere in systemsettings and it can override ours.
