LG monitor hotplug on DPMS wake causes several apps to either crash or lose their windows on output recovery

I'll try to log some WAYLAND_DEBUG logs for the relevant services tonight, if I can get anything useful out of it. Both of the panels are Wayland apps, so it should be fairly easy to WAYLAND_DEBUG either of them and coax some display output recovery attempts.

Logs attached to bug report.

This honestly sounds like a bug in wf-panel and sfwbar, I can't imagine what wayfire would do so that you don't see any panels there. Do the output(s) work fine otherwise after the dpms cycle?

[kode54]

Probably is a bug for those panels, but it doesn't happen on labwc. The outputs are otherwise usable after the output recovery. Maybe output recovery isn't recovering layer shell windows?

You hopefully shouldn't lose the bar on monitor disconnect with the latest git version of sfwbar. There seems to have been a change in behaviour in gtk/gtk-layer-shell/wlroots interaction over the last few months.
Previously, we could watch for output destruction and graciously unmap the bar on the event. Now the bar surface gets unmapped before we're notified of the output destruction and we need to handle the "delete" event on the bar sent by gtk-layer-shell.

I’m sorry I didn’t report these directly to your repository, I had initially thought they were compositor problems. I’ll try to remember reporting application/compositor interactions to both ends where possible.

edit: and thanks for catching this post.
