Vaniila xfce uses main panel on top not on bottom like manjaro does. This can invite some irritations, i.e. notifications in the tray are not visible because they are shown “under” the panel.
So, try with panel on top as a workaround, if you are fine with a slightly different look.
@maycne.sonahoz@banjo: Thanks alot for your input and ideas. I tried them all and played around with several panel and display settings and I somehow fixed my problem. My findings:
Same problem with other themes. I’m using one of the default themes which ships with Manjaro. Themes seems unrelated to this issue
Panel was already at the very bottom, although the problem definitly occurs if I place the panel somewhere in between top and bottom. So panel and menu overlaps in that case which might make sense for that usecase
Putting the panel on top didn’t solve the overlapping problem either. Anyways, thanks for the historical explanation which sounds comprehensible
So, the problem occurs particularly on my external monitor. I toggled several settings in display settings and also panel settings. It’s working now. No overlapping between panel and menu anymore. I bet I can reproduce it again if I a play around more, so there is a bug when using external monitors.
I leave my settings like that for now and in case it occurs again, I now know how to possibly work around it.
Update: A couple minutes later and the icon menus appear now on the other screen. Quickfix: Panel preferences > Lock panel: Off
