Weird quality loss and saturation when scaling
I have recorded some gameplays on a game called Tibia, it is a pixeled game, everytime I try to scale the video, it loses quality (more than it supposed to) and get more saturated.
The weird thing is, when I click on scale and move the cursor to the right (to scale up) and hold the button, it scale the video as it supposed to (without losing to much quality and with the source saturation).

But when I drop the button (to apply the changes to the video), the video loses more quality and get more saturated.

Here is 2 pictures with the differences.

Why is this happening? I don't have problems scaling with other editors.
