Double-clicking on the “puck” inside one of the new color wheels seems to cause instant crash. I verified on two different Windows 10 machines running latest 2021.5 build.
I tried double-clicking because I didn’t see a reset button and thought that might be how one resets the hue/sat change (Adobe design language).
Video is 30 fps 1920x1080 ProRes4444. Session is 16-bit.
Node is “Color Correct” - node tree is default for a paint setup with color correct placed just after the source.
Sometimes needs to be a triple-click to crash.
