Continuous warning message causing game to run slow, Tiled GPU perf. warning: Anyone fix this

Tiled GPU perf. warning: RenderTexture color surface (0x0) was not cleared/discarded, doing <run with profiler for info>

This warning appears in my console now for some reason when i run the game with the play button. The game becomes very slow and choppy when before it ran totally fine, very smooth in fact. I have a feeling it has something to do with this message that continuously repeats in the console. How do i fix this problem and bring the game back to normal speed? Thanks everyone.
