Lookup TOP Bug - zooming network in/out fluctuates values

I am working on a project that relies heavily on LUT effects. I am running into a weird issue wherein my zooming in/out the TD network changes the results of the Lookup TOP.

The alpha channel jumps between 1 and 0.5, when I expect 1. Unfortunately I can only get the desired result at a particular zoom level when viewing the Lookup TOP. If I am outside any of the components containing the Lookup TOPs, the values are all wrong…

Definitely strange. Could you post an example file so we can reproduce your settings. I can not reproduce in the simple case. (make smaller snippet or lock the unput OPs if you want)

Also, what is your GPU and driver version?

Hey Cutmod, any feedback on this?
