Bug ID: 402834 Summary: Multiple successive gradients drawn one above other produce undesired banding and color variations Product: krita Version: git master Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: General Assignee: krita-bugs-n...@kde.org Reporter: ra...@raghukamath.com Target Milestone: --- Created attachment 117268 --> https://bugs.kde.org/attachment.cgi?id=117268&action=edit gradient banding SUMMARY When applying multiple successive gradients (foreground to transparency) one above other, we get bandings and undesired color variations. According to discussion on IRC this is due to dithering problem. the bug is seen prominently when working with colors close to black and you draw it on a new layer. Drawing on an opaque white layer reduces the banding a bit. I have attached a png file with multiple gradients you can see banding in the middle, and if you zoom in you can see reds and greens in the colors. this becomes a hassle when color picking and painting too. STEPS TO REPRODUCE 1. Open a New document in Krita, switch color to close to black near red spectrum. 2. Choose the gradient tool and go and adding radial gradient successively one above another OBSERVED RESULT Bandings appear when applying successive gradients EXPECTED RESULT gradients should be dithered and smooth gradation should be produces SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.14.4 Qt Version: 5.12.0 KDE Frameworks Version: 5.53.0 -- You are receiving this mail because: You are watching all bug changes.
