I'm having an issue where black "v" shapes or jagged lines show up in my render. They almost look as though the image is being ripped apart and the black background underneath is showing through.
Through process of elimination I've narrowed down the source of the problem to be the Render Layer titled "text shadows". This layer consists of duplicate text objects that I've added a blur node to in the compositor to create a shadow effect. I've tried to troubleshoot the problem by removing nodes in the compositor, hiding or deleting my mask object in each scene, and adjusting the position of the text shadow objects in y space. The only way I've found to remove the black shapes is to turn the "text shadows" render layer off altogether in the Render Layer panel. After doing so the render turns out fine, but I can't achieve the look I'm going for without the shadows behind the text. Any insight into what is causing this issue and how to prevent it would be extremely helpful. Also, I'll include the .blend. I'm using Blender Internal.
