[Designer 2.5.1] Expanding rounded corner strokes creates jagged nodes

[LCamachoDesign]

If an object has rounded corners that only round the outside angle of the shape, but not the inside, upon expanding the stroke of the said object the outside nodes will be sharp instead of smooth. This is actually hard to explain in words, so I've included a video showing the issue and a sample file for you to try.

In any case, here's my attempt to provide a steps to recreate:

1. Create a shape, such as a rectangle
2. Give it a rather thick stroke such as 15pt or more
3. Set the corners to rounded
4. Input a rather low corner value such as 3% for example
5. Expand the stroke of the object
6. Notice the jagged outside edges
7. Undo back to step 4
8. Try again with corner value 0 and repeat
9. See the stroke expands correctly
10. Undo back to step 4
11. Try again with a large corner value such as 30%
12. See the stroke also expands correctly

This bug is not limited to shape objects, it also happens with simple curves, provided they have a low value rounded corners. This bug does not seem to happen with any other corner type. Also, this bug can be inconsistent, I've seen shapes that follow the "rounded outside sharp inside" rule expand correctly.

Thanks!

Thanks @LCamachoDesign

I can reproduce that, I'll pass it along to the devs.

Any update to this as I have the same issue when using the contour tool or the stroke then expanding it getting the sharp corners.

Hello and welcome.

When the developers have found a solution, the Affinity Info Bot will provide a notification of when it will be available..

The same happens on macOS version of the software and also with open paths. Any news on when this gets resolved?

I’m also experiencing this on both the iPad and Windows editions. I can literally see the point at which the contour tool adds the jagged redundant anchors.

SO noticed there was actually an update available to 2.5.6 but sadly, there was no fix for this insane issue ...

What is going on here? An essential vector editing feature like expand stroke has been broken for months?? This is making me second guess switching back to affinity ...

yet another update to 2.5.7 and this issue is not only not fixed but zero feedback from this company of when it will be ....
