Buffer Expansion - Kernel

[dkt0]

Expanding the buffer completely corrupts the GPU path. Even when I just make it make the layer blue and red, the layer is just completely corrupted when I add it with other effects. The corruption does not happen at all when I use it with AE's built-in effects (like Transform or Directional Blur). It does not make any sense. Ever since I added that expansion, the GPU path does not work at all with my other effects. This is my Directional Blur plugin when it's above my Exposure/Gamma effect. It happens with ALL of my effects.

Update, after more debugging, the issue is that the next effect is getting the expanded input world instead of the cropped one. I have no idea why this happens and how to fix it, but all I can say is that, this does not happen when I add it with AE's built-in effects. I am clearly missing smth here.

Update again, I fixed the issue.
