When editing a transition, in particular, when changing keyframes for fade in/out, etc., preview render chunks covered by this transition do not get invalidated. This causes timeline play to be out of sync with the actual timeline clip/transition configuration. Reproducible: Always

This now seems to be extremely sensitive to editing transitions and usually stops preview rendering with the an error "preview rendering failed, check your parameters". At this time, preview rendering hasn't yet reached the transition that was edited. For what it's worth, the preview rendering zone spans the whole project. This render abort may be caused by my particular project setup, but at this time it makes editing transitions while preview rendering being active no fun, because rendering gets aborted as soon as I touch something. Alas, my setup is as follows: 1. track: logo clip spanning the full width of the project; it has an affine transition with the bottom-most track. Track is unlocked. 2. track: titling with an affine transition: as soon as I edit the transition all preview rendering stops, even if rendering hasn't yet reached the part covered by the transition.
I only now notice that albeit the error message appearing in the status bar and the preview render progress bar turning red the rendering seems to resume after some seconds when not touching the preview render button. Strange...
Doing more editing I now don't get the error message anymore when editing transitions. Seems to be a bug related to my specific project setup. I will wait for it to pop up again and then I hopefully may be able to also come up with a simple regression project. So I'm closing this for now. Jean-Baptiste, thank you very much again for your hard work! It is much appreciated!
