junovhs Posted March 10, 2019 Share Posted March 10, 2019 I'm having this recurring issue, where if I clip something to a shape/curve at an angle the original shape/curve fill bleeds into the edge, which is particularly obvious when clipping a light color to a dark color as shown here: Can anybody help? Much appreciated clipping mask error.afdesign Quote Link to comment Share on other sites More sharing options...
firstdefence Posted March 10, 2019 Share Posted March 10, 2019 Make sure you have Precise clipping enabled in Preferences: Performance. You also have a slight colour shift between the nested colour and the background Quote iMac 27" 2019 Somona 14.3.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

gdenby Posted March 10, 2019 Share Posted March 10, 2019 Hi, junovhs, This is a known problem, and one that is not trivial to do away with in the code. From what I gather, the anti-aliasing routine picks up a trace of a background color. The work around is to add a centered edge stroke. In your file, if a stroke of the same aqua color is placed on the black shape, the dashed line goes away. EDIT, and what firstdefence said.

Wow, I was just about to post this as a bug... lucky I found this thread! What a silly thing to disable by default... although, I've noticed that the app does become quite sluggish quite quickly. Illustrator is always slow, but never bogs down. Designer is fast on small documents, but quickly becomes sluggish. Quote Link to comment Share on other sites More sharing options...
