Bug ID: 404133 Summary: Artifacts when painting in RGB 32-bit float/channel Product: krita Version: nightly build (please specify the git hash!) Platform: Manjaro OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Brush engines Assignee: krita-bugs-n...@kde.org Reporter: manuel.snudl.zeid...@gmail.com Target Milestone: --- Created attachment 117943 --> https://bugs.kde.org/attachment.cgi?id=117943&action=edit Exported image showing artifacts I attached an image to illustrate. The .kra file is beyond the size limit. I only used paint and fill layers with normal blend mode. Visual artifacts occur in the nightly appimage when painting in RGB 32-bit float - not however in 16f, 16i or 8i and also not in LAB, CYMK, XYZ or Grayscale in any combination. It is most obvious with a pixel engine brush using wide spacing, but also occurs with the particle brush and the tangent normal brush. The tangent normal brush seems to be an exception, here the artifacts seem to apply once per painted brush tip instead of aligning to the canvas. I didn't notice it with the shape, sketch or color smudge engines. In 4.1.7 this problem didn't occur using the same file.
