Using BCC+Color Gradient in both Vegas Pro 20 & 21 with keyframing used for Angle (and also Size in a 2nd test), playback of the event on VP's timeline with the gradient affect applied worked without a problem in both VP20 & 21.

Thanks, I just tried it again on a video, separately Size & then Angle again, same as before the gradient stayed static 🤔
This shows that when Video FX dialog is open, it seriously affects the playback performance of FX. I've met it before. Even sometimes, the playhead disappears.
This is an old problem of Vegas. Hope Vegas Team can fix it.

Just been playing with this..,
Added an adjustment event above a text track & a green background solid colour,
Adding BCC+Color Gradient to the adjustment event, with Angle keyframes set it moves when played without the need to switch to Pan/crop,
Tried it again with BCC+Color Gradient on the text, no movement when played as before.
Therefore, this may not be a problem that can be stably reproduced. It usually happens on a PC with poor performance. Or a PC with good performance but running more tasks at the same time.
I noticed an interesting phenomenon: when playing, both the screen widgets and Video FX dialog's playhead are static.
