Render Mask not clearing VFB after each frame

[ruven_hinder]

I’m trying to work with the rendermask object feature. However when I render an animation it wont clear the vfb after each frame and just stacks the new image on top which makes the feature useless for me. Am I missing some checkbox or something? I know there is a setting in 3ds Max and Maya but I couldn’t find one in the Blender UI.

Below you can see the examples.

Thanks for your help
