The color picker does not give the color of the picked pixel

[yannlossouarn]

Describe the bug
When I use the color picker on tight areas (like a part of a text letter), CCA does not give the color of the text but apparently the color of the background.

Desktop (please complete the following information):

• OS: MacOS Tahoe
• Version 26.0.1

To Reproduce
Steps to reproduce the behavior:

Pick a color on an area that shows various colours (e.g. text on a background)

Expected behavior
I would expect the colour of the picked pixel to be returned by CCA.

Screenshots

Additional context

• The problem occurs only if I use it on my Macbook Pro 14" internal monitor. CCA works as expected if I use the color picker on a Dell external monitor.
• The problem occurs whichever software the color is picked in (e.g. I tried inside Safari, Chrome, Firefox and Figma)
• The problem might be related to the recent MacOS upgrade.
• I am not sure that is related, but I noticed the "target" inside the zoom selector of the color picker does not allow picking each pixel, it seems there are doubled pixels, and I can only pick 1 pixel for each 2x2 pixel square.

I have encountered the same issue in macOS Tahoe 26.0.1.

It appears the problem does not occur with all resolutions. The default 1512x982 resolution on my 14" Macbook Pro is affected, but not the 1920x1200 one. I switched to the latter, as a workaround, I hope my eyes will resist such a resolution on such a small screen. :)

I also have the same problem. It appears the picker doesn't select the colour that is visible in the small zoomed-in-window, but the colour that is under the actual position of the mouse.

(also on Mac OS Tahoe. Changing resolution didn't work for me...)

Looks like the issue is resolved in the latest macOS update 26.1 @TomRaaff @yannlossouarn

Yes, I've verified that it now works properly again on Mac OS 26.1. Thank you for letting me know!
