[Bug]: $stippled_hr broken on wayland (kde 6.5.2)

[cylgalad]

What happened?

Setting out_to_wayland to true, conky displays the top (in my case, time and date) in gray, gets frozen with nothing else displayed.
I removed the $stippled_hr that was just underneath and it works again.
I have another part between two $stippled_hr, and they show as a full gray-ish line instead.
I ended up replacing them all by $hr.

Version

1.22.2-pre-a4fd63c1

Which OS/distro are you seeing the problem on?

Edit: changed the config for a usable one for testing.

Confirmed on my laptop with both kde and sway (gnome and weston aren't compatible with the wayland protocol conky uses).
