I recently went from version 19.10.20 to 20.02.17. Everything is smoother. I only noticed one bug.
I usually work with multiple files: different resolution, framerate, color range.
When I have 3 video tracks and I change the color range property of an item on the second track, the program will glitch out and the first clip in the playlist will be replaced with the item I changed the color range.
If I have 4 video tracks and I change the color range property of an item on the second track, the program will glitch out and the second clip in the playlist will be replaced with the item I changed the color range.
This has never happened to me in the old (19.10.20 or older) versions.
