This has always been super annoying, I just have gotten to use to using right click to select my color instead of left click.
Basically left clicking any color in the color picker that overlaps the Explorer window will lead to unwanted actions, in the gif example, this is placing the part inside another part. The intended behavior is to click to select the color and have the Explore not register the click
This also occurred with the old 64 pallet color picker so it’s nothing new
I’m using a Macbook Pro with retina Display if that makes a difference.
