I’ve installed Workbench from Flathub, on Fedora 39. Most of the samples seem to work great, but for example, the Navigation Split View doesn’t. It pops up the expected editor window, but the Preview is empty, and tapping “Run” does nothing. Same with Header Bar, and a few others.
This seems like a good opportunity for me to learn how to diagnose weirdness with Flatpak, so I can file a good bug report, but I don’t know where to start - which is why I’m asking here.
To start, what’s the best way to see the log output of a flatpak app?
