Hi all. The name of this topic pretty much says it all. I'm not sure what could be causing this. I'm using Vegas 19 on this computer, and adding a new video track will make the colors of the video tracks below darker. My friend doesn't have that problem, and he also uses Vegas 19. What could possibly be causing this? I find this so weird.

BTW, I'm using Windows 10 Pro, 64-Bit; I have an Intel(R) Core(TM) i7-10700F CPU @ 2.90GHz, and 32637 MB RAM, with a GeForce RTX 3060 Ti. Thanks in advance.

Edit: I found the problema:that the default compositing mode that activates was set to something other than source alpha, so I can fix this, but every time I add a new video track, I have to fix it manually. Is there a way to change the default compositing mode?
