Possible import bug

I have a generated file (attached: out.gds) that will display differently depending on whether it is opened using LayoutEditor when compared to Klayout or GenISys' BEAMER software. The list of coordinates that make up the polygon are also different. I don't know whether this is a bug in LayoutEditor, if it's undefined behavior in my generated file (using gdspy1.6), or otherwise. The list of vertices that is displayed corresponds correctly with rendered feature in both cases. However, the list of vertices is different between the two editors. The cell named 'cir_r_48' contains an example of the error. I attached pictures of the error if it cannot be replicated on other's systems.

After using the online GDSII viewer on this website, it looks like the error is not present. Therefore, here is my system information: LayoutEditor build: 20190820 OS: MacOS 10.13.6 CPU: Intel(R) Core(TM) i5-5350U CPU

Please disable the option "remove not needed points" under setup/shapes/general/polygon_check. In case the check is enabled, all polygons on load and after some polygon operations are checked on points not required for that polygon. So spikes without an area are removed as well as 3 points in a line. In the cell 'cir_r_48' one point is removed that should not be removed. So a corner is slightly reduced. This will be fixed with the next update. Thanks for mentioning this issue!
