Pattern Tile Seam lines are visible when imported in Photoshop or saved via Export for Screens
Can we please find a way to fix those tiny 0.5 px seam lines we ALL have had to deal with for years? The ones that you see when you zoom in or out at certain levels? The ones that don't apparently print? However, they for sure show up when importing patterns into Photoshop, so they aren't just imaginary. When building a Photoshop pattern that begins as a vector pattern, it becomes a nightmare having to meticulously clone them out. Please fix this if at all possible!

Hi AI team, Is there any progress here? Can you provide a status update?
Its a serious issue for users of the pattern maker.
From what I see is that it happens when bitmaps are used in patterns.Is this an underlying issue with antialiasing and the rendering engine? Sounds similar to how AI also creates an hairline AA edge on asset exports when they arent aligned to the pixel grid or use dimensions that contain half pixels. (is 100.5 px)

This is, without a doubt a bug. Not just rendering. Take a clean, repeatable pattern, export to JPG with Art optimized. Then there WILL be seams when tested in Photoshop. This does not happen as much of the time when exported to PNG. Why has this bug been around for over 7 years??????? What s the root of the problem and what s the workaround??

When I export designs (via Export for screens) with patterns that have either been expanded or not I find that I get verticle and horizontal lines in my pattern. This is not present in the app, only on the resulting PDF/JPG/PNG exported file. I found this doesn't not happen when using the legacy Save for Web option. This is not an AA issue. Both are set to art optimized and the results are very different.

In my searching many people say it is not a bug, just a pesky screen rendering problem. If the exterior edge of the pattern did not anti alias the problem would be fixed. Patterns require a hard edge when creating. Just leave the edges hard. Then anti-alias the elements within the pattern.
Transferring files from illustrator to photoshop is indeed a challenge.
I can reproduce this bug. Please contact me. This should work better.

This is an AA-issue that they really should look into solving. It's been around for too long. :/

I admit this isn't a "new feature" but is so needed. That tiny, 0.5 pixel width "seam" line is an absolute nightmare to deal with. Sure we've always been told it won't "print", but it sure shows up when importing a pattern into Photoshop. Cloning the seam line out is WAY too much work. There has to be a way to fix this seam.
