Is the menu in the normal place on the window or has the desktop moved it?

So Bob I see this about once or twice a month using Wayland, usually when I open a dialog that I haven't opened in a while. It's usually roughly in the right "location" it's just tiny. If I fix the window it generally stays fixed for a while, but then reverts eventually. It happens when the dialog or menu is opened, not during interaction with the dialog or menu (it just spawns tiny).
I can't reliably reproduce it as I haven't figured out what triggers the reversion, but it seems to be a function of either time or maybe version upgrades? For example, I might take benchmarks once or twice a year so almost every time I open the benchmark window it's tiny, but if I open it a few days after my last benchmark its always fine. So my advice to reproduce would be to go to a wayland environment and try opening a bunch of different settings windows you haven't used in a while.
EDIT: In testing it looks like every second or third time I open the "Get Cover Art from the Internet" dialog it's tiny, so I'll second cochinada's suggestion of using that to reproduce the issue as it reliably fails here. I hadn't noticed because I only use wayland on client machines where I don't do cover art operations. It doesn't happen that frequently to most other windows although appears to affect almost every dialog window sometimes.

Thanks to everyone who responded. I appreciate it.
The Dell laptop has two hard drives and came that way from Dell when I originally bought it as a Windows box. Ubuntu is now the only operating system on the machine and it is running on the 124GB drive. The music data is stored in a folder I called MC Music on a 1TB drive rather than in the default Ubuntu music folder.
I just booted up the laptop to grab the file path to post here and this time around Media Center is finding the files. All I did after booting the machine was double click on Media Center icon in the left toolbar on the desktop to open the app. Then I double clicked on several different songs including songs I know I had trouble with in the past and also other songs in the library.
I then decided to restart the machine again to see what it would do and this time, literally minutes later, Media Center gave me the File Could Not Be Found error again on all songs.
So I exited Media Center, double clicked on the files folder and then reopened Media Center and it found the songs again.
Here's the path as seen in Media Center: \media\sophie\Data\JRMCMusic . When I look on the drive called Data to see the file path there of the audio file outside of Media Center, it is the same except for the slashes showing in the opposite direction.
Zydex, yes, it was a Windows library back up. Can I edit platform.jmd after I have restored the library? I did search and only found plaftorm.jmd in the zip file where I saved the library backup before installing it.
zybex:
Yes, you can (and need to) edit the platform.jmd, but not the one in the ZIP file. You should find the actual folder where the library lives - check in ~/.jriver/Media Center 33/Library

Hi Zybex,
I went looking for the JRiver folder. I discovered that inside the JRiver program files folder, there is both a folder called MC33 and a folder called Media Center 33. Could this be the source of my problem? In neither of them is there a platform.jmd file.
Should I have both of these folders, MC33 and Media Center 33? Is this an artifact of trying to install a library backup from Windows? There is no library folder in either the MC33 or Media Center 33 folder.
How do I resolve the lack of a platform.jmd file?
zybex:
Not sure if the linux install has both an MC33 and a Media Center 33 folder, it's possible. Or maybe you tried to install it twice?
The platform.jmd not missing, you just can't find it. The library folder contains many .jmd files (like the contents of that ZIP backup) - it has to be there somewhere. The ".jriver" folder may be hidden to you because it starts with a dot.
You can see the current path to your library in MC - click on the library name on the tree:
