I cannot reproduce the problem.
Which editor/panel are you trying to sample a color?

After restarting blender, I cannot reproduce either. But after a while, the bug spontaneously appears

@cheteron I think @mano-wii asked, what property are you changing that does this.

Does this happen when you click on File > Defaults > Load Factory Settings? This is to determine if some unofficial addon does this.

Now, I work in a blender in 2.90 beta, and so far I have not noticed the effect. It can appear spontaneously. Last time appeared when sculpting in sculpt vertex painting in alpha version. I think that at the factory settings, I just can't catch it on purpose

Can confirm.
With factory settings, only changing color picker type to square (SV + H):
Windows 7, Blender version: 2.90.0 Beta, branch: master, commit date: 2020-07-26 20:02, hash: 04195b1e74
Without default version can confirm on version 2.82, 2.80
It's not appearing at hue with a period of 1/6: 0.000, 0.167, 0.333, 0.500, 0.667, 0.833, 1.000. If you bug hue all the way to the 1.000 it'll chance to 0.000.
Default scene, adding material and editing material base color. It's minor but still existing.

Default scene, changing color in preferences.

I think this is the same issue as in #69562 (Manipulating saturation of colors (e.g via HSV or RGB curves, but also within color picker) shifts HUE), will merge these reports.
