Bug? Edges of shapes dissapear at differing zoom levels, or during export.

[ZanaGB]

I think i may have encountered a bug with the software.

I am doing a design for a project, and, i am finding that the edges of the shapes vanish at certain levels of zoom, it's not consistant at which levels, or which edges of the shape get cut off during zoom, but it is also a problem during export ( see attatchments ) where it cuts off other parts of the edges.

Given the simplicity of these shapes, i don't think i'm running into some sort of limit, but it's somewhat concerning.

Also attached is the current WIP for the project if it's needed as well as a full-size png export. Hopefully this helps figuring out the issue.

I did share this with a friend who also uses version 2.0.x of the software and the issue happens to them as well

Is this a bug?

I should probably also mention this bug happens on macOS 13.3 running on an M1 Mac Studio

Select the object (in this case the yellow-orange stroke), then in the Stoke Panel, change the Miter value from the default to a higher number. Try 2 or 3. Then zoom in and out and you should see it remain the same. It does on my Mac with v2.0.4.

Each corner which is not being rendered consistently has multiple overlapping nodes instead of one node. Delete the superfluous nodes to get the expected rendering.

You could perhaps do this better with the appearance panel. Just add two more strokes aligned to the outside with progressively smaller widths.

Hey, Changing the Mitre to 3 seems to have fixed the issue, the edges don't look wonky on rendering, either!

Thanks!

Glad it worked for you.

@ZanaGB The "Miter" setting for strokes determines whether you will have a totally sharp corner or not (in any non-smooth connection). More acute angles require a higher miter setting in order to give you a totally sharp point. I created a series of triangles in the attached AD file, and the width of the stroke didn't seem to matter, just the angle. A 90° angle can retain a sharp angle with a fairly low miter setting of 1.5. A very small, sharp angle may require a miter setting 4, 5, 10 or higher.

I ran this simple test because I wasn't sure myself whether the thickness of the stroke required a different miter value to retain a sharp point, but at least in this test, it appears not. Maybe there are circumstances where this breaks down, but if so, I didn't see it.

I suspect that as well as the mitter issue, it might be an issue of misplaced nodes as ",,," said. However, as this updated PNG ( and project file ) show, changing the setting to "3" did indeed fix the wonkyness i was experiencing. At this point i don't know what to say. It should not work, but it's currently working. At least while i was adding the text around. Renders fine and looks fine on Designer's viewport.
