Adjustment Layer cause Image to "jump" with color correction

I have an timeremapped timelape where i color corrected some aspects. I notice some "jumping" of the footage when the adjustment layer is active, it jumps/streches the image a little bit. I checked several times that or original is not jumping at all, only in combination with the adjustment layer i get those result. On the Adjustment Layer there is no keyframe for scale or so which could cause this, just color correction. 

What i noticed that even when i pre-render the clip i get red sections in the timelime around that area where i can see the "jump" , i would expect that those turn green after pre-render.

Just by playing around with the layer i managed to get rid of the problem, which makes no sense: I simply remove the Adjustment layer and just do an "undo" to bring it back. Viola i get what i expected from the beginning. Those tiny bugs where as user you have no clue what cause them makes me feel this is never really tested, to me is looks like a caching issue. Please fix ASAP!
