--- Comment #7 from Michael Weghorn <m.weghorn at posteo.de> ---
The current approach of using a standalone window (class BubbleWindow, declared
in vcl/inc/bubblewindow.hxx ) doesn't work on Wayland, because it's not
possible to position a window at an arbitrary location there.
As a consequence, the window simply shows up at the centre of the existing LO
window. For gtk3, it additionally looks very odd and has a window frame.

Screenshots:

* kf5: attachment 199069 from bug 157521

I think a different approach is needed (at least for these 2 VCL plugins). Some
potential approaches might be:

* replace both, the button in the menubar and the "bubble window" by a
completely different solution (e.g. an info bar or a dialog, but that might be
more disruptive than the current solution - at least if it works correctly)
* Leave the button in the menubar and show the text in a tooltip for that
button instead of the custom "bubble window".

CC'ing the UX team, as this can't be fixed without a redesign, IIUC.


Following are sample steps to reproduce.

# Prerequisites:

* Wayland session on Linux
* an official TDF build of LibreOffice (that has the update check enabled, e.g.
25.2.0 downloaded from the TDF website)

# Sammple steps to reproduce:

1) download the LanguageTool extension [1], version 6.3 (not the latest
version!), direct link: [2]
2) start LibreOffice
3) install the extension: "Tools" -> "Extension" -> "Add", select the file
downloaded in step 1, select "Only for me"
4) restart LibreOffice, open Writer
5) wait until a notification shows up that extension updates are available
(takes ~30 seconds in my setup)

# Actual result:

* A button shows up in the menu bar (OK)
* a "bubble" shows up with this message: "Updates for extensions are available.
Click the icon for more information."
* That bubble is misplaced, in the middle of the LibreOffice window

Screenshots will be attached.

# Expected result:

The bubble should be located right below the menubar button, pointing to it
because that button is the "icon" that should be clicked to get more
information.

# More information

It works fine with the "gen" VCL plugin (which runs on XWayland, not native
Wayland)
