panel spacing gradually increases until useless
Using gnome-shell 3.28.3, I find that over time, the spacing on the panel will increase until nothing is really visible and I have to restart gnome-shell in order to restore it.
Here is a screenshot of the panel with the increased spacing:
Here is the panel normally, like right after I [re-]start gnome-shell:
Frankly, even after gnome-shell is [re-]started there is so much space empty and wasted while the date is still truncated, but that is probably another issue/ticket.
