I wanted to try out the Linux app on Ubuntu (downloaded the .deb file), see how it compared to Obsidian (which is sadly a little awkward in terms of sync and config).

Unfortunately the desktop version is unusable - it automatically maximises itself and then gets stuck in a loop, constantly trying to resize. Trying to make the window smaller makes it go similarly crazy and it will just revert to filling the screen again.

That's unfortunately a non-starter.
