BUG: Masking a Lumetri adjustment layer transforms the underlying footage...
weird mask bug here.
I have footage. I put an adjustment layer above it. I put Lumetri in it. I go and draw a mask to make the adjustment just inside that mask.... the normal relighting routine.
Usually this would work flawlessly. But today when I tried it it results in the underlying image data being masked, yes. But the footage is also squeezed into that area.
With other effects, like Curves. It works as expected. But with the lumetri effect it squishes the footage like a canadian comedian squishes heads... See attached image
I guess I can't mask adjustments layers with lumetri effects now... shame... it was such a powerful tool.

Very bad problem, still there in version 16.0.0.
