Hi, this should be fixed with Krita 5.0, as we made the gradients wide-gamut and high-bit depth aware. Can you try to see if it's still happening? Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone! Sorry for late reply. I repeated the same test at krita 5.0.2 with the same configuration and gradient file, but color banding still exists, as attachment 3 [details] shows.
