[Green Screen LUT]

Doesn't work as described but still nice. All pictures I tried had the background go dark grey and the subject black (instead of white as needed). So I always have to apply a levels adjustmens to get the background white and then invert the image to have a working mask with white subject and black background. With that process you get good results from this.

[1.9 slow]

Also having very poor performance. If I use a paintbrush and quickly draw some lines, I can literally sit there and watch as the lines are drawn. My graphics cards doesn't give me the option of hardware acceleration so that is disabled by default. It's almost unusable and I'm afraid I have to go back to 1.8

[Really slow performance after updating to 1.9]

Hardware acceleration is deactivated on my office PC cause the graphics card is not up to snuff. Still 1.9 is waaay slower than 1.8.5

I'm thinking of going back for the time being and wait for updates. Haven't had any crashes though.
