Hi

I am running Ubuntu 16.04 and trinity.


There is an interesting app, called mathpix (which transforms png into
latex)

https://snapcraft.io/mathpix-snipping-tool

It has to be installed via 

sudo snap install mathpix-snipping-tool

I did this and when I start with ubuntu vanilla desktop I am able to
start the app. However in trinity I find the start icon, in lost+found:
I start the app

 ps aux | grep mathpix 

Tells me 

oub      17567  0.1  1.7 3424960 143548 ?      Sl   18:46   0:03 mathpix-snipping-tool

But nothing happens, no icon, no app is seen.

What shall I do?

Thanks
