[Daniel van Vugt (vanvugt)]

Looks like a bug in the ubuntu-terminal-app snap. It's running Xmir instead of rendering to Mir natively...

Since it's running under Xmir, the transparency could be related to black GLX apps bug 1510025. And this might also then be a duplicate of bug 1510386.

The core issue however is that your ubuntu-terminal-app is running Xmir, so let's fix that.
