The Color Panels are so slow you can't reliable shift the adjustment

The color panel adjustments, even simple things like tempurature or balance, are so slow and lagging that as you make an adjustment, you have to move your mouse and then wait for a second or two for the image color to catach up, which means half the time you click the mouse DONE and then the color catches up and the final image is too green because it was lagging so far behind the actual adjustment.  

You cannot ship it this way!  It is so inferior to the the sliders.  It is SO SLOW.  And I am on a very fast computer.  And I don’t have a ton of effects on the videos, mostly cuts only.  It is just deathly slow to adjust color in the new color mode.  You have to fix this.
