Streaks coming off top and bottom of image/video/text layers

Too much going on to actualyl make sense of it, but my guess would be that these artifacts relate to using time-remapping and effects at the same time. It's always best to pre-compose time-remapped stuff first to ensure consistent rendering behavior and avoid temporal sampling errors that some time-aware effects and functions may produce based on looking at the wrong frame.

I'm not sure what layer is selected or what was done to that layer. You have not shown us the modified properties of the layer or layers that are giving you problems. 

I would start the troubleshooting process by making sure that Fast Previews in the comp panel is set to Final Quality, solo the layer that you think is causing problems, then start looking for the problem as you turn on one layer at a time. When you find the problem layer select it and press 'uu' to reveal all modified properties. Start turning off effects or resetting values until you find out what is causing the problem. If you can't figure it out post a screenshot that shows us the details.
