Sketch image BG displays white

Hey hey,

Have just been using the sketching tool (pretty much for the first time). All in all it works pretty great on the iPad, with the background colour matching the theme and displaying the chosen background type (lined, boxes, etc). All in all looks great.

The same image on the Mac comes in with a white background, which, tbh, looks pretty terrible with darker themes. Not sure if this is a bug or not (thoughit should match the background colour as it’s saved as a png, so would have a transparent background).

If not a bug, it would be great if the Mac display of sketches would match the iOS devices; feels like expected behaviour. Also, is it possible to enable the sketch blocks on Mac (or is the pen kit iOS only). Would be great to use it on the desktop with a Wacom tablet…
