Dropping to lock screen kills phosh (clock/arrow-up/keyboard/titlebar)

What problem did you encounter

Pushing the lock-button, consistently (when done after hours of operation), kills the clock, titlebar, arrow-up, keyboard icons (assuming this is 'phosh'), after a bit of time it drops to the lockscreen and then after unlocking it does indeed resume visibility of the clock, titlebar, arrow-up, and keyboard icons (phosh).

What is the current behaviour?

Lockscreen button kills phosh.

What is the expected behaviour?

Lockscreen button just drops to lockscreen.

Description: Pure Wayland shell for mobile devices
 Phosh is a simple shell for Wayland compositors speaking the layer-surface
 protocol. It currently supports
 .
  * a lockscreen
  * brightness control and nighlight
  * the gcr system-prompter interface
  * acting as a polkit auth agent
  * enough of org.gnome.Mutter.DisplayConfig to make gnome-settings-daemon happy
  * a homebutton that toggles a simple favorites menu
  * status icons for battery, wwan and wifi
 .
 If you're not working on a Wayland compositor then this package is likely not
 very useful for you.
