Importing PNGs

I am trying import a png into Corel Draw and never seem to get a descent vector output, after trying all the different available options (quick trace, high quality image, etc.). Seems all the lines are squiggly, fat and thin, gray and black, etc. The Png files are typically not super high resolution, so the prigram doesn't reproduce very well. The original would be fine, if it kept straight lines, like original, but of course no bitmap jaggies.

Trying to import this, without literally hours of rework
