what is and how can i stop the constant "canceling..." in the compositer? At the moment I'm working on a project and I was using the compositor. I don't know what started it, but at the top of my screen, there is a bar that constantly says "canceling"

also, my render layer node outputs are flickering



I'm making a graphics design thing with animation nodes, that's what you can see in the compositor. I 'm trying to put a vintage noise over it that's what you can see playing in the top.



and next to that my compositor is very very slow.

I have tried a lot of stuff to make it go away. I have restarted blender, I have reinstalled blender and I have tried to remake my whole node setup. but nothing works. the only way to make the "canceling" go away is closing the composetor window. but the moment I open it again it comes back.

I really hope someone can help me with this problem
I was able to get it to stop by deleting the viewer node from my node group in the animation nodes add-on. I was using a viewer node to confirm my output was correct when sending some text data. From now on I know just to use it to check and then delete it. Probably has something to do with the viewer node also being used in the compositing tab?
