paolo.limoncelli Posted December 21, 2024 Posted December 21, 2024 Hi there, I reported this bug in the past, but it seems the recent update has caused it to resurface. My system Affinity Photo 2.6.0 (2984) Mac Studio 2023 Apple M2 Ultra macOS 14.7.1 Wacom Cintiq 27" QHD (DTK-2700) Driver 6.4.8-2 Simply take the Smudge Brush tool and use any brush that supports pressure to reveal areas displaying a central square, smudged with alpha, even when the area itself is a different color. SmudgeToolGlitches.mp4 An educated guess: I don't believe this is related to the recent propagation of Wet Edges setting, as shown in the video above, the issue persists even when Wet Edges is disabled, and Wet Edges is the only "new" feature for his kind off tool since 1.X I guess... It is like the very first click is picked from an empty (transparent) area, regardless cursor's position. I'll try to explain. Below you can see this behaviour using a mouse and a debug brush. The image here consists of two layers: a dark blue background layer and a top layer with red and yellow areas. The Smudge Tool, should smudge so it is meant to blend or displace existing pixels on a layer, and this video shows how it works DebugNib_mouseClicks.mp4 When I select the top layer and use the Smudge Tool, I'm basically "sampling" the area I clicked and transferring that data elsewhere. For instance, if I click in an "empty" (transparent) area and then click on a filled (colored) area, the tool behaves like an eraser, transferring the transparency sampled earlier onto the coloured area. Logically, if I click on a transparent area, nothing should happen when smudging elsewhere, anyway it makes sense if you want to bring "transparency in", you're gradually mixing with transparency (basically erasing). Also, the exact opposite happens if I click on a coloured area and click outside, acting like a stamp/cloning tool. And this makes sense, since the the engine is gradually blending towards transparency the area that has been sampled. Using a graphic tablet now the artifacts shown in the first video can be consistently replicated and undisclosed. DebugNib_PenTablet.mp4 A the end of the video I'm turning off the blue layer to show the erased areas. By reducing the brush spacing, the behaviour becomes more logical; however, the initial sampling of transparent areas and the resulting erasure should not be there since I'm starting from a filled/opaque area. And this is exactly what happens in the first video. Am I wrong? Cheers, Paolo Benfischer 1 Quote DAUB® Brushes making tools for artists, illustrators and doodlers
paolo.limoncelli Posted December 21, 2024 Author Posted December 21, 2024 Also... Just to add further information. Moving strength up to 100% on a simple opaque pixel layer the Smudge Brush acts as a pure eraser... SudgeBrush_100%.mp4 So for some reasons it is sampling transparent pixels for the very first click, no matter where you are.

Staff Pauls Posted December 22, 2024 Staff Posted December 22, 2024 I've been able to recreate some blocky textures so far but it's not as bad as your examples shown. Are you using a mouse or graphics tablet in the videos ? Also when you get the chance can you try with the use Internal GPU option enabled as well to see if the behaviour is any different Quote

Will check the CPU/GPU settings and let you know! Cheers! Pauls 1 Quote DAUB® Brushes making tools for artists, illustrators and doodlers
