Why my stroke is pixelated ?

have   the same problem, don't know why it  happens. For me i was apply stroke to smart object  what contain vector graphics

So I have had this problem too for a while, and I have found a solution using 'Unsharp Mask' that fixed this jaggy looking stroke issue for me.

I too was slamming my head against the wall because this problem was so frustrating xD.

All the answers that I found on the internet where either workarounds that don't directly fix the problem or answers from people who think it just all looks pixelated anyway and don't see the need to fix it.

I made a sheet describing the steps I took to fix this problem. All examples use the same stroke settings. In example 2 I recreated the problem with the jaggy looking stroke and I fixed it in example 3.

I hope this helps a lot of people out

In some previous desing software I saw this, is not a problem, because is not pixelated. The first think that u have to try before do another thing is Export this to PNG and then check, the most of time (if is not the software or something) you will see it perfect.

Why this happen?? Well let suponse that the render in Adobe is in low quality for be more fast in performance, when u export, it do it depend the dpi that u use and size.. If u has work in 3D software before, suponse that when u are making the design is 50 samples and when u export is 100 samples (just a example).

And check the resolution of your monitor (just in case) if you can connect it via VDI, will be much better. In some cases, I dont know why some monitors (I guess) you look like if it have Not Anti-alias. But obviously in this case is not the monitor. (is just a suggestion).

Hope this help u.

Try applying a gaussian blur and see if that helps soften up the edges.

Try setting your brush to 100% Hardness and 1% Spacing, use your brush and then try the Stroke and the stroke should be somewhat smoother.

How did you apply the stroke?
