Problem with Color picker set to CMYK color wheel

If the color picker has been previously set to CMYK color wheel (not sliders) -

If you want to change an object color by selecting it, then going to Properties>Display color and choose “Other” (to bring up the picker panel) - the panel takes 4-5 seconds to open here. If the panel is set to any other “wheel” method, it opens faster, but still a tiny lag. If set to any of the ‘slider’ methods, it opens instantly. Tested in (7.5.21068.13001, 2021-03-09)

Hi Mitch - thanks, I’ll check it. It seems OK here - what you do not show in the clip is going back to the CMYK wheel - is that slow again, or just the first time?

Happens every time here…

I have the same problem, slow :slightly_smiling_face:

Hi all - some people here can reproduce the problem, at least on 7.5. Still fine for me in any build so far … but I am old and lame. @Helvetosaur - a shot in the dark, but can you see if shrinking the dialog to hide the color list, and the ‘extra’ controls that show up when it is expanded, makes any difference?
RH-63244 Color Picker: CMYK wheel lags

Not older and lamer than me… by a long shot… :stuck_out_tongue_winking_eye:

Yep - good guess:

But it looks like only when the wheel reaches a certain size that it lags…

Yep, OK, thanks - Vanessa was able to see this as well.

Yay Vane!

I also reported a similar bug here: Wish (Rhino 7): Bring back the convenient selection of colour from the "Select color" menu - #13 by Rhino_Bulgaria

The problem seems to be related to the size of the window and the HVS wheel.

Hi
The same problem came back again in 7.8 :sweat_smile:
