I'll tag this today using Lubuntu noble..

Booted live on my primary box
- dell [optiplex] 7050 (i5-6500, 16gb, intel hd530/i915, amd cedar radeon)

On boot only 3 monitors connected to internal intel card are
functional.. not a problem; open monitor.settings & enable the others..
& they have wallpapers & look good.

next I adjust the alignment of monitors to match my setup, and suddenly
4.4 of the monitors are black (no wallpaper) and part of the wallpaper
only shows on one monitor...

if I right click the black monitors I'm getting OBMENU appearing and not
expected LXQt menu...

I try re-adjusting the monitors again (numerous times) and no useful
change... exit & re-enter monitor.settings (panel was still
visible/usable!) & try again a few times, no go..

Exit & re-open monitor.settings (again) & this time I get wallpapers on
all monitors & operation is EXACTLY was I'd want.. even have alignment
of screens matching my setup..

People only do this screen alignment RARELY; on first setup, and on a
'blue moon' when they adjust their offices etc.. and in all cases where
I experience this, I can usually resolve it in ~5 minutes.

I don't see it as critical, but its a little frustrating, and could be
very confusing the first time.

In support; I'll just suggest end-users who experience it just replace
`openbox` with `xfwm4` and the issue doesn't happen.

Title:
  lubuntu - strange movement of wallpaper on monitor.settings change (or
  next login)

Status in OpenBox:
  Confirmed
Status in lubuntu-default-settings package in Ubuntu:
  New
Status in openbox package in Ubuntu:
  New

Bug description:
  File upstream as https://bugzilla.icculus.org/show_bug.cgi?id=6566

  Originally Lubuntu 19.10 daily
  deb cdrom:[Lubuntu 19.10 _Eoan Ermine_ - Beta amd64 (20190926.1)]/ eoan main multiverse restricted universe

  I adjusted the monitor.settings to match my setup, also changing the
  primary screen and it did exactly what I wanted, however the wallpaper
  appears to have been misplaced; the top.of.wallpaper is now displayed
  on my bottom.monitor with my top.monitor having no wallpaper  (this
  bottom half of wallpaper isn't shown)

  The importance of this is probably MINIMAL.

  I have been able to re-create it, but it only seems to occur with a
  specific setup, and is likely linked to
  https://github.com/lxqt/lxqt/issues/1709 or
  https://github.com/lxqt/lxqt/issues/1704  (though upstream suspect
  those two bugs & others are linked).

  Note:   The right-click behavior on the screen without wallpaper is
  likely to be Openbox only (ie. openbox menu), where as the screen with
  wallpaper will remain Lubuntu/LXQt behavior.

  ---
  LXQt 0.16 on Lubuntu Hirsute; this has been re-created.  Also note (see comments #10-12)
  - On the TOP.monitor I'm getting OPENBOX menu on right click
  - On the BOTTOM.monitor, I'm getting standard LXQt menu

  Also occurs on opensuse tumbleweed & debian bullseye, & fedora 33

  Filed upstream as https://github.com/lxqt/lxqt/issues/1925  (closed as
  only occurs with openbox)
