Color picker applet doesn't pick a color. When added for first time, only gets black color. If history is cleared, doesn't pick any color.

1. Use color picker.

No color is picked.

Clicked color is picked.

What exactly do you mean by "Use color picker."? Use it how? What *specifically* are you doing that isn't working?

Bug of colour picker & showing Colour Dialogue
Comment 4 Kath 2022-07-14 13:01:22 UTC
I have faced this bug too, let me see if I can provide more information

The colour picker widget does not select any colours if you use the button. At first it will display pure black (#000000) in the colour history, and when you pick a colour via the button, instead of picking the colour where you click it will place "#000000" into your clipboard and keep the existing black in history.
If you clear history, this black colour will go away, but no further colours will be picked correctly.

Interestingly, Right click > Open Colour Dialogue, and using "Pick Screen Color" will work correctly. I have demonstrated this as best as I can in a videos I have attached

colourpicker_bug_1 shows the interaction with the black
colourpicker_bug_2 shows the Colour Dialogue too

Operating System: Fedora Linux 36
KDE Plasma Version: 5.25.3
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.3

Processors: 16 × Intel® Core™ i9-9900K CPU @ 3.60GHz
Memory: 15.3 GiB of RAM
Graphics Processor: NVIDIA GeForce GTX 1080 Ti/PCIe/SSE2

I have tried this in Wayland:
- Button picking, still broken as described above
- Colour Dialogue > "Pick Screen Color" Does not work. The "Cursor at X, Y" does not update as I move my mouse over the screen. It will only update while I move it on the Colour Dialogue window. It does not select a colour correctly

If there is anything further you need from me, please do say and I will do my best to help. This is my first time reporting kde bugs so I'm happy to learn more.

I am experiencing this issue on Arch Linux KDE on multiple devices (desktops and laptops). Happens with nvidia propriety driver on desktop and Intel graphics on laptop. All Arch systems are fully updated.

Bug 454974 reports that the result is "returns black". This bug appears to be different and not a duplicate of 454974. Furthermore, this bug is not resolved as of plasmashell 5.25.4 while 454974 was marked as fixed in 5.24.7.

Same in Manjaro. Just stopped working suddenly.
