Hello everyone. I tried today to check the Smart Mark option that was added in the recent update of Vegas Pro 20. I can tell.... it works pretty good but I see the problem in which the behaviour of the FX Effect seems unstable. Sometimes doing undo option by CTRL+Z or by another method results in seeing the error as shown in the video:

Computer specs:

Windows 11 x64

AMD Ryzen 5 5600x

Memory: 32 GB (4x8GB) 3600MHz CL14

GPU: ASUS GeForce RTX 3060 Ti DUAL OC 8GB

Hard Drives: 2x 1 TB NVME Kingston 1TB M.2 PCIe Gen4 NVMe KC3000 (I have also Crucial one but Vegas and OS are installed on these ones)

I do not know if it is a normal matter in which undoing a mask is impossible to revert (I am not an expert in this program but I am trying to learn as much as possible)

if it's a simple bug then ok, I guess it is just a matter of time
