[bug] Changing terminal font to Inter crashes the app into a blank window — no way to recover from inside the app #3513

I changed my terminal font to Inter from the appearance settings. Right after applying it, the terminal view did render in Inter briefly, but the character spacing was really off — clearly broken since Inter isn't a monospace font. Then Superset started crashing. The main window just comes up blank every time I open it. Since the setting got saved, every relaunch hits the same crash, and I couldn't get into settings to change it back because nothing renders.

The only way I got the app working again was to go into the SQLite database it stores settings in (~/.superset/local.db, settings table) and manually null out the terminal_font_family column. After that it launched fine and fell back to the default font. That's a pretty rough recovery path for anyone who isn't comfortable editing a database by hand.

I didn't try reproducing with any other fonts — I didn't want to risk crashing the app again while I had work going.

Environment: Superset 1.5.0, macOS.
