Tero,

I think it happens, because the previews are deleted when you change to Sofware only.

look in the picture below, when I make a change to colors, red color bar appears on the top of a clip meaning that this segment of the sequence does not have a rendered preview file associated with it.

So when i I render within the timeline, changes are visible.
am really confused.

p.s. I updated my video drivers

WOW, I did change it to software only and strange thing happened:

It only shows changes when I am grabbing and dragging the Lumetri sliders (saturation,contrast, exposure), however when I release it, it changes are not displayed

In picture below, I tweaked the colors but there is no effect on a program monitor however,

On picture below, I opened Media Export and can see the changes
