PL8 BUG help request: Luminosity and Hue Mask trapezoid selection

DxO PhotoLab macOS topics
1

I just upgraded to PL8 on 2023 M2 Max MacBook Pro running Sequoia 15.5. Using either the Luminosity or Hue Mask, I can’t select and drag the triangles on the righthand side of the trapezoid using the cursor. I can select and drag the triangles on the lefthand side. Also, adjusting the right side of the trapezoid by directly changing the numbers in the corresponding value fields does work. I tried to upload an image, with green checkmarks showing the triangles I can move by clicking and dragging, and the red Xs for the triangles I can’t move.

Has anyone encountered this bug before or have an ideas for fixing or troubleshooting?

Thanks

no issues here using sequoia 15.5

No problem either with Win 10.
Is it on several images or not?
Can you send an image with the problem so that we try ?

Thanks for the responses.

It is on every image I have tried including cr3, tif, jpeg files. I tried the luminance mask in FP7 and it works normally in that application. I tried deleting and reinstalling PL8, and restarting my computer, and clearing the cache, and none of those resolved the issue.

I contacted DxO and am waiting to hear back.

No problem here either.
Can you share a raw file with us as suggested?

No problem here either. I’m also on Sequoia 15.5 and the most recent version of PL (8.7).
