Both are menu's not appearing where expected (just not the same place)

QA-test on dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt) today on 19.04 daily - issue remains.

QA-test (19.04 daily) on same dell 755 (c2d, 8gb, radeon rv610)
i changed the right-side monitor so it was rotated left (look at picture for clue)

TODAY the panel menu was NOT appearing as described for this bug, but on display0 (the other monitor far right, so nearby) as far right on it's panel as possible. This actually looks better (not sitting in the middle of nowhere, but attached to the panel alas wrong screen) but requires more mouse movement than just the vertical.

The way I have monitors setup can be seen in picture, as can menu. My mouse didn't show, but it was on the right (portrait) screen over the menu bottom left corner (of right monitor).

QA-test (19.04 daily) on same dell 755 (c2d, 8gb, radeon rv610)
i changed the right-side monitor so it was rotated left (look at picture for clue)
head /etc/apt/sources.list says i'm using 20190318

TODAY the panel menu was NOT appearing as it did in prior (#6) comment but back to ~7.5cm (i believe it's higher!) above the panel on display1.

The way I have monitors setup matches the screencapture from #6, plus additional panel setup the same way I believe. This is unexpected.

Both different to last comment, and I believe higher than original 5.5cm (quite a bit higher than panel on other display where it used to be only slightly higher)

dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

adjust monitors to match my setup (change left & right position;
..
I'll explore https://bugs.launchpad.net/ubuntu/+source/lxqt-panel/+bug/1810075 as these are the same monitors, but on this box the default panel is drawn on the portrait display, so the additional panel will be created on the landscape monitor...

I didn't expect this (same monitors, but different cables & box) - yet when I add the second panel on now-left monitor, the now-right-portrait menu is appearing ~7cm above the panel :(

Note: this is occurring to the menu the system booted with (on portrait display), not the newly added panel.

QA-TEST 2019-04-05 (AEST (au) local time) -- comments from test

dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt)
two displays, right is portrait mode - adjusted monitor.settings to match my setup; for some reason it's seeing resolution as differing (they should be identical) but i'm ignoring this for now (it has occurred before so i'm blaming hardware (screen or cable))
..
added second panel to second display... add widgets a little like default panel -- it's opening menu ~13.5cm above panel today?? and ~9.5cm below top of screen!! it's getting higher again! (measurements are using a ruler & to closest half-cm; possibly unhelpful for debugging but it's easy...)

this could be related to resolution (dell displays should be same resolution; i'm blaming hardware issue for resolution diff), AND this is occurring on the monitor that monitor.settings has declared is lower res (1024x768 instead of 1280x1024 the monitor should be getting).

Lubuntu 19.10 QA-test.

Picture of issue reported in comments of qa-test. My cursor is over the icon "Funny Cockatoo Video - Crazy Corellas.." but the menu opens much higher on the display than expected.

This box (d755-8) has two displays, the right is portrait-left tilted (why the menu on landscape-left display is not at bottom). The top of displays was roughly equal (on picture you can see it's not perfectly aligned).

Lubuntu 20.04 QA-test (from QA-test comments)
dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

check install media; boot, adjust displays to match my setup (swap left-right, my right is portrait-left tilted, my-left display is primary, top of displays are level, so portrait-right-tilted extends lower than landscape-left display)
add panel to each display has panel at bottom, populate with menu, desktops, volume & clock
generic play - menu now opens (landscape-menu) as if bottom-of-display panel is same height as the other screen, or near 9cm above panel - https://bugs.launchpad.net/ubuntu/+source/lxqt-panel/+bug/1810075

This bug is marked against `lxqt-panel`; and was filed upstream (LXQt). Upstream LXQt linked a number of bugs, and have now said they aren't LXQt bugs, but an bug/issue in `openbox`.

This issue requires a specific screen setup to get it to occur, so it's pretty minor.

Fresh Lubuntu hirsute (2020-02-22.1) QA-test install on d755-8 box

this issue is still occurring on LXQt 0.16

guiverc@d755-8:~$ lxqt-about --version
lxqt-about 0.16.0
liblxqt 0.16.0
Qt 5.15.2

The image shows the actual Monitor positions relative to each other (left display), yet when pressing PrintScreen there is a GAP between the positions??

The gap is reflected when you move the mouse between them, however I can move the windows around, click Apply & Save, then put them back to the positions that match my setup & same issue will re-occur.

This bug though is the MENU appearing WELL ABOVE the panel on the right display (ie. issue still occurs)

I'll need to file this picture upstream

I just re-created this on
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)
using Lubuntu hirsute daily (live QA-test).

To achieve it I have
- two monitors (DVI-I-1 & DP-1 listed in Monitor.Settings)
- Monitor.Settings, my DP-1 is left, DVI-I-1 is right
- right monitor or my DVI-I-1 which is rotated portrait-left.

panels on both monitors, the portrait-left monitor (DVI-I-1) menu appears in the middle of the screen

I'm doing testing for bug https://bugs.launchpad.net/ubuntu/+source/lxqt-config/+bug/1882411 on tumbleweed and this issue [1810075] is occurring there

opensuse VERSION_ID = 2021.06.28

lxqt 0.17.0
liblxqt 0.17.0
Qt 5.15.2

WM in use is xfwm4 (I did not notice it before I logged out whilst using openbox.. but I'm not looking for this bug as currently testing for a different 1882411 bug so as to file upstream, and may have only used quicklaunch items not menu)

Lubuntu jammy daily (LXQt still 0.17.1)

and adjusted screens to match this setup; with panel on my-bottom display; but menu is opening on the my-top display; ie. ~16 inches away from mouse pointer (which is bottom-left-corner of lower-display)

(attached picture includes pointer; which is bottom-left of screen; yet menu has opened on my upper-display so half up the image..)

Lubuntu jammy.1 QA-test (20220729.1) and this occurred on
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

one screen set to be above the other, panel is on my-bottom display, but right-click on panel items and the menu or options appear on my-top display; ie. a foot above where the pointer is or full-screen height above where expected.

I install `xfwm4` on the live system, switched to it & logged out, logged in a whilst the LXQt session started (and a dialog opened on the wrong display relating to device/USB plugged-in/ejection; once LXQt was fully running everything is good.

After switch to XFWM4 & once settled in, volume, nm-tray, qclipper, MENU & even 'removal media/devices manager' (what appeared on other screen during login) are opening just above the panel now.

Does this issue relate instead of openbox?

Unexpected, but I had this occur today too....

lxqt-panel is at the bottom of of my lower display (I have Monitor.Preferences viewable on screen so layout can be seen), so clicking for menu to appear would have users expect the menu to appear on that monitor, alas menu appears on top/other display

removed upstream LXQt issue as they closed report; it only occurs when openbox is selected as WM...

(this report no doubt is duplicate of another which was reported upstream with openbox, alas has had no action)...

It's not just the menu that appears on other screen, but all icons/items (eg. right-click a window, click volume widget etc) appear on top monitor/display

Priority is MINIMAL/VERY-LOW as it only happens with a specific screen orientation, plus if displays are configured as mine are (if top/bottom are reversed the issue does NOT occur). It's not video card affected as it impacts multiple boxes; using hp8200 currently

(removed link to https://github.com/lxqt/lxqt/issues/1709 as rejected by LXQt as only occurs on openbox or something)
