Hello,
I am using plasma under wayland.
I have in pamac, dolphin, kdenlive and various other applications the problem that the menus, dropdown, right click are not displayed in the correct position.
In Pamac the buttons (Apply) are at the top instead of at the bottom.
I have attached some screenshots to illustrate the problem.
I don’t know if it’s relevant to the problem, but I’m using a two monitor setup.
Greetings Michael
Hm. I also use Plasma wayland session and while I did have that issue at some point, but I haven’t seen it in some months.
Your profile says you use kernel 5.8, so maybe update that (either kernel or profile). 
My profile is outdated, I will update it. I use kernel 5.19.1-3-MANJARO.
After I did today’s update and KDE Plasma is now in version 5.25.5, the problems are unfortunately still there.
I have now found out, if I align my two monitors at the top edge(see screenshot) it fits with the menu and the right click in Dolphin. As soon as I put them back the way they are, the problem is there again. This is a temporary solution but it doesn’t match my actual arrangement of the monitors, so it’s really unattractive.
Can anyone here give me a solution to this problem?
The problem in Pamac with the dropdown list still exists.
Oh, you have multiple monitors!
Seems the issue could be connected to multiple monitor setups with different resolutions maybe. 
yes, it seems so. But under x11 the problem does not exist, so it seems to be Wayland.
Try to disconnect one of both monitors, if the issue persists?
yes, the problem persists. Now it has even occurred again although I have aligned the monitors as described above in the settings, so this does not seem to help after all.
It seems that something is wrong in your KDE environment.
I can not reproduce this issue when using my two same monitors and KDE Plasma Wayland.
This is a bug in Qt 5 - Qt 6.3 : [QTBUG-85297] Menu location is offset depending on xdg_output.logical_layout in sway - Qt Bug Tracker
In Qt. 6.4 this is finally fixed, but unfortunately it will take ages until all application use this Qt version.
And the devs decided that this is a behaviour change and will most likely not be backported to Qt 6.3 and absolutely not to Qt 5…
The workaround with aligning the two displays on the top edge is the only one that i know and the one that i am also using.
It’s really not a great UX, but you will get used to it quickly.
Why can’t I reproduce this problem?
Can you compare with my versions here:
KDE Plasma Version: 5.25.5
KDE Frameworks Version: 5.97.0
Qt Version: 5.15.5
Kernel Version: 5.19.7-1-MANJARO (64-bit)
Graphics Platform: Wayland
Maybe it is due to the different resolutions. In my case, there are not two identical monitors. One has Full HD and the other WQHD.
Thank you for the answer. I will leave it then also that I align the monitors at the top edge and hope that the developers then update as soon as possible to Qt 6.3. I had said earlier that it didn’t work for me with it either, that was wrong, KDE just hadn’t saved my settings and had reset it back to the original settings.

Okay, we have the same versions and use AMD devices.
Maybe some desktop effects cause the issue:
KDE menu → Search: Desktop Effects → Try to disable features if it works.
I just tried it and with the new user it is exactly the same. When I align both monitors on the top edge everything is ok, when I align them on the bottom edge(or even centered) the menus are shifted.
You can switch back to Xorg and wait so long for Qt 6.4+ for many KDE applications.
Yes, I could do that, but unfortunately freesync doesn’t work reasonably under x.org, so I’d like to stick with wayland. I will have to live with the workaround then… Thanks a lot!
Does the shifted dropdown list have something to do with the same bug, because it is still shifted, no matter how I arrange the monitors.
I have disabled all effects, but it is exactly the same behavior. I have made a video of it for better understanding.
