# png viewer not opening

Using Linux subsystem for windows with ubuntu 20.04 and sagemath 9.0

When I try to open a png plot from sagemath I get the message that it opens however nothing happens.

Launched png viewer for Graphics object consisting of 1 graphics primitive


However sagemath viewer is configured correctly

sage: viewer.png_viewer()
'xdg-open'


And the most peculiar thing is that by attempting to open a png file from shell trough sagemath it can with an error that persists even if I open the png without sagemath.

sage -sh xdg-open test.png


or

xdg-open test.png


Opens the png successfully and returns this error message

Error: no "view" rule for type "image/png" passed its test case

And when I add --debug=1 the command is no longer recognized
This must be some oddity of the Linux subsystem for Windows, because sage -sh xdg-open test.png works well with native Ubuntu 20.04.
