I'm trying to do simple background with plain bg and a border for a tooltip by hand. However I seem to have problem with corners.

Without the paths (border) I don't seem to have this problem. As if calculated widths/heights are not the same as I have them in mind.

Anyone have any ideas what is wrong? Looking for others' files didn't help much as they are done with Inkscape and looking into the source that is produced by it is something I'd like to avoid as much as possible to keep my sanity.

Try using 1px wide rectangles instead of borders. It should probably do the trick.

It works. Thank you :}
