[REGRESSION] Backspace no longer works in host/rootfs make run virtiocon0
Bisected to the following range: 1e9c681 lib/nixpkgs.default.nix: update to nixos-unstable-small f41b4ab tools: move lsvm out of subdirectory 5ad749b tools: enable clippy::ptr-as-ptr lint a4d7aa9 tools: enable clippy::map-unwrap-or lint 3451250 host/rootfs: group VMM-backing services 99f09ab pkgs: remove dbus overlay Most likely something in the Nixpkgs upgrade. Needs further bisection. To reproduce: cd host/rootfs nix-shell --run 'make clean && make run' View → virtiocon0 Wait for kernel messages to finish Try typing, see that backspace doesn't work

Most likely looking remaining candidate is 6725ca2dabdd ("gtk3: 3.24.50 → 3.24.51").
I also found https://gitlab.com/qemu-project/qemu/-/issues/3191, which looks like the same thing. Doesn't look like there's a patch yet. I'll continue with the bisect in case it helps them to have the specific change that caused the regression.
Surprisingly I can reproduce on that commit's parent, so it's not the gtk3 upgrade. Glib upgrade, maybe?
