OK, I gave the Snap another try and this time the application loaded for me. It looks perfect. I don't know what is causing the font distortions from the direct installed deb versions of both the standard deb and the ptb version.
(This is how it's supposed to look and this is the Snap version of the application, now working.)
That said when I was removing the Snap version previously the menu item which at that point did not load the application was left behind after the removal so I deleted it in the menu editor. Could someone please tell me if there is a way to re-install the menus or could a fellow Discord snap user provide the command to run and I'll recreate the item manually?
I don't know much about Snaps despite hearing about them off and on. I've generally stuck with PPAs and debs in the past.
Thanks again for any assistance!
EDIT: Okay, I followed one of my other snaps to this address and found what I needed minus the application icon:
/var/lib/snapd/desktop
Could someone please tell me for future reference where Snap keeps its icons for installed applications? I'm using one I downloaded off of Google for now, but since Snap is intended to be the way forward I'd appreciate a pointer to where to find the icons of Snap applications.
Thanks again.
