Hi, all. Hoping not to duplicate anything that has already been asked. Tried my best due diligence poking around the forum and the almighty Google, but perhaps my Google-fu is just broken tonight.

I've decided to have a little fun and jump over to -current, starting to wean myself off a long-term relationship with 14.2. So far, things have gone well and I'm happy with it. I just have one minor, albeit puzzling issue with Plasma5 I'm trying to sort out.

On both a fresh install on one of my laptops and on an upgrade of my desktop (I know, bad me for not getting clean first), I have a strange issue with moving panels around, whether the default or newly-created. When I go into Edit mode, and try to bring up the panel options, I don't get the usual "popup" with the "screen edge" button to move the panel around and the other options buttons. Instead I have a small rectangular window that seems to render slightly off-screen and has no controls/handles/widgets.

I messed around with all kinds of settings: compositor on/off at startup, different sessions (Wayland, Failsafe, normal X), changing window effects options, changing themes...none of it affects the behavior. For now I was able to get my panel up to the top where I like it by adding new panels till one automatically chose the top screen edge, then deleted the rest and went from there. However, it's still bugging me that I can't get that "options" bar to popup.

Side note...I also had the issue with the PlasmoidPopupsContainer.qm[l] error in the tray, as seen in my screenshot, but fixed that by renaming the file extension as mentioned in other posts about the same.

Screenshot attached to this post is of my desktop, shortly after firing up Plasma5 for the first time and getting ready to customize (my conky bar, leftover from 14.2 configs, can be seen hiding behind the default panel). Does anyone have any suggestions of what may be going wrong here? Not sure what log files, if any, might tell me what the deal is (missing dependency, "oops" in a config file, etc). Could it be a KDE5 bug I should be talking to the KDE project folks about?

Desktop is a Dell Optiplex 390 with ATI Radeon R7 250 (radeon driver), laptop is a Lenovo T440 with Intel Haswell integrated graphics (i915 driver). Both pure x64, no multilib.

Thanks!

I also had issue with *.qm files instead of having *.qml files. There were a couple of them. You can find them with:
Most of them belong to package plasma-workspace. I reinstalled the package.

So first step, make sure you no longer have any .qm files in /usr/share/plasma.

Right you are, problem solved. Output of find located another 6 files with ".qm" extensions.

I threw together the following bash one-liner to parse through and clean it up quickly:

Didn't even need to logout afterward, just opened panel Edit, and there were the droids I've been looking for. Thanks for your help! Greatly appreciated.

FWIW, I have 3 installations with Plasma 5 and had the .qm issue only on one of them.
On the system that had the issue, I checked plasma-workspace package content (in /var/log/packages) and it showed the *.qm files. The same with the packages which contained the other qm files (I think latte-dock was one of them). I reinstalled those packages and issue was solved.
I didn't investigate why the installed packages had those .qm files.
Packages didn't have qm files in the other 2 systems.
