The Pick color tool does not select the correct color when selecting a color from the desktop. When using the Color --> Pick Color tool either from the Styling Dock or Layer Properties the tool makes the color transparent.

From your video seems like you are picking the color from outside the QGIS application window, just curious: does it work if you pick a color from within the QGIS app?

No, when using the Pick color tool from the dropdown color widget, the color is set to transparent even if I pick a color within the QGIS application. However, if I select Choose color... --> Sample color it works. From there I can select a color from within QGIS or from other places on my desktop.

There are a couple of issues here:
1 - inconsistency (by design apparently): you need to keep the left mouse button pressed to pick the color
2 - the cursor does not change to the color picker as expected

Ok, I have a fix for item 2 above.
But I'm hesitant: why do we have/need two different ways to pick a color? Wouldn't be better to just keep the "Sample color" from "Choose color" action?
What we should probably do is to make the "Pick color" action activate the color widget (like the "Choose color..." action does) and activate the "Sample color" action within the color widget: this way we have a consistent behavior and less (duplicated) code to maintain.
In other words, I suggest to make the "Pick color" action a shortcut for "Choose color..." -> "Sample color".

This hopefully fixes the issue, works for me on win 10 and Linux but on Win 10 the cursor does not always immediately changes to a picker: sometimes it takes a few seconds or a few mouse moves, I'm not sure if this is something due to my relatively slow Win 10 VM.
Please give this a try.
