People had different theories why phosh-osk-stub woudn't use the whole display width on wider displays so I was buckling up for a full afternoon of debugging sizing issues but as it turns out after a couple of minutes we were just missing a tightening-threshold in a HdyClamp: Rest of the afternoon saved thanks to #gtk inspector 🎉
@leimon I didn't upload phosh-osk-stub (https://gitlab.gnome.org/guidog/phosh-osk-stub) to Byzantium as I don't consider it production ready (it fits my personal use cases though). Older versions are in Octarine and recent ones are in Pureos Crimson and Debian testing. It builds and runs on Byzantium fine though (I'm using `l5-fetch-next phosh-osk-stub` to install it there).
