There was a bug in Corel 2023 with bitmaps that if it was rotated and you turned on Object Hinting it would get distorted. Is that bug still in 2024?
What previous versions that didn't have the issue are you referring to?
I would say 2022 and earlier were no issues.
I tested 2018 and did not see the distortion that I see in 2024 with object hinting turned on, I however did see some other issues with rotated images both with and without object hinting turned on that 2024 does not have, interesting.
What does object hinting do for you?
