Objects set to fill but are not closed disappear if Filled Rendering set to on

[LightBurn (Oz)]

It’s on the list to fix. We don’t recommend using ‘filled rendering’ for much other than spot checking partially because of this. Determining whether a shape is closed or not is complex - it came up recently here:

Layer's colors on canvas drawing priority

There are a few other gotchas to filled rendering that need to be addressed. The biggest being that when you are creating a shape with lines, but on a layer set to fill, it doesn’t draw the shape at all unless it’s closed. The code to determine whether a shape is closed or not is complicated, so I need to cache that value in the shapes and update it when they change, like I do with some others.
