A yellow bar appears under my compostion window above my time line. I can't even type a sentence with the type tool without it trying to render every letter. Its making my computer and my worklow painfully slow and it's also irritating me. I don't kno why it suddenly started to do this while I was editing audio layers. Can anyone tell me how to turn it off? Please?
Update: it also makes it so my RAM preview only renders 1 frame at a time and it cannot store any rendered frames so it has to always start over and rerender everything.
