Ive been using vegas pro 16 since 2018 and have had little issues, but suddenly out of nowhere when I try to edit and use the mask tool my display fps just drops. Any other time the fps in the display is pretty much a constant 60, but when I try to use the mask tool it will drop to about 45-50, and when it goes to another clip itll drop to almost 0. This wasnt happening a couple weeks ago and seemed to have come out of nowhere and I dont know why. And it ONLY seems to happen when im using the mask tool. Doesnt seem to happen with anything else from what I can tell.
