As shown in the above image, when I modified the preferred output format to Rec. 709 Linear, the color sample tool displayed incorrect color. I think this should be a bug.
First of all, your display doesn’t support HDR.
Thank you for your reply, but all the colors meet expectations. Only the color sampling tool displays abnormal colors, so I feel that there must be something wrong.
What percentage is the blend setting on in tool options?
Thanks, they are default settings, I’ve tried to report the bug anyway.
If you provide the link to the bug, someone can try to replicate the problem and then hit the confirm button on the bug for you.
This is the link to report this bug, I tried to fix it, but I failed.
Well, now I’ve tried to fix it, but I’m not quite sure if I fixed it the right way…
