Drawn mask, gradient, "curved" if lens correction applied
I've got a picture with a 14 mm f/2.8 Samyang and an EOS 6D MkII.
I've use the lens correction. Distorsion was corrected.
Further, I want to apply a tonality curve with a drawn mask.
But the limit of the mask is no more a straight line.
It is shaped (curved) the opposite the lens correction is done.
So the shape vary from the top of the picture to the bottom.
See the attached screenshots.
How can I staigthen this limit?

That's not a bug but a feature.
If you have created a mask on a picture for a given area when distorting it (Liquify, perspective correction or lens correction) you want the area to be preserved.

Wanted to record here that I also face the same problem with some lenses that have pretty huge distortions.
If you disable the lens corrections, the gradient mask is straight but the horizon is not.
If you enable the corrections, it's the other way around.
Of course there's the workaround where you apply corrections to the raw file first, then export to TIFF or PNG and continue your work on that one. It can be cumbersome, though.
