phosh lockscreen unresponsive immediately after starting

When Phosh first starts (e.g. on boot), the lockscreen is unresponsive to input for some number of seconds, >5 (I haven't timed it). It seems kinda similar to previous issues with pipewire's startup, but it shouldn't be that... It started after Phosh was upgraded to 0.12.0.
