Bug reports go where?

I just downloaded LT a few minutes ago and started following some videos on getting started.
When I got to the “Open Workspace” part the popup opened but all of the text is rendered as square blocks.
Where would I post this question?
I am running Ubuntu Linux 19.04 with 32 GiB of ram.

Thanks for any help you can provide.
