Evening folks! I am having this weird problem. I'll number the issues:
Preview is stretching when I open other windows, like fx, generators, etc. It doesn't happen when using crop and pan, althought there's a little lag
I can only see applied fx when I close the fx window or whatever window is open
It looks like this started after a GPU driver update. But I already performed a clean install of drivers and Vegas itself.
I'll edit this as I see other issues. Sorry for bad english
