Picking a screen color does not work in White Balance LMS space.
Built from git master on 2021-09-14.
Steps to reproduce:
- Put a clip on the timeline
- Add effect: White balance (LMS space)
- On the white balance effect, select the dropper and click on a color on the screen that should be white.
Expected result: The color selected, and the filter adjusted so that the color selected appears white.
Actual result: Color selected appears black. Clip appears black. When toggling visibility of the effect, you can see that the clip is still there, it's just the filter that has a bad value.
