Database list missing!

Hopefully that image paste worked, can't link out to imgur--

There should be a long list of databases on this server, but it's missing entirely--like it's been reduced to Height 0 or otherwise hidden somehow, not sure. I tried going to Tools > Preferences > Restore Defaults, but it didn't bring it back.

Any idea how I can get the ol DB list back? Thanks!

Hah, never mind, solved it--DPI scaling issue for some reason. I toggled on blob preview yesterday, I bet in making space for that it confused Heidi.

Thanks!
