No, this is something new.  I suspect Qt 5.15.8 might have changed
something in its multi-monitor support which may have broken something
somewhere, probably in
linphone-app/src/components/notifier/Notifier.cpp:Notifier::createNotification().

It would help a lot if:

- you could confirm that the behaviour is still as expected if you disable one
  of your monitors,

- you could give the exact dimensions of your monitors and the exact
  coordinates and dimensions of the notification windows and the white
  rectangles,

- you could paste any stdout/stderr or logfile output that contains
  the string "Primary screen" if it appears anywhere,

- you could maybe prepare screenshot(s) that are not too large
  (e.g. maybe convert to 256 colour PNG, remove any Desktop wallpaper
  etc.) and post them here.

It would be important to know if the notification windows are actually
in the very center or slightly offset somehow in case the bug is
related to subpixel support.

As for how soon this bug will be fixed: I can't tell.  Everyone in
Qt-land will probably start the migration to Qt 6 in the near future
if they haven't already, and thus probably deprioritize polish-related
issues like this.

Since I use a single-monitor setup I won't notice if this bug still
persists, so consider posting here after a new version has been
uploaded whether or not it still manifests.

Regards.
