LM 18.3 KDE - menus not appearing in several applications

In certain applications (Firefox, Opera, Linphone, Deadbeef (music player), FileZilla, Audacity...) when I try to click the menu (e.g. File, Edit, View, or the 3-line menu button in Firefox), no menu appears. However, I notice that the cursor changes color, as if the menu has opened, and if I click randomly in the area where the menu should be, I get an appropriate response, e.g. if I click Help and then a few space down, I might get the "About" window of that application. So the menu is there, but not showing up.

I first noticed this problem in Firefox and posted about it here. It has received no replies after 2 days, and I've discovered the problem goes well beyond Firefox.

I'm unable to see anything if I open Driver Manager, although it too seems it might be there but just invisible, as nothing else responds until I hit ESC.

I've tried rebooting into previous kernels. Current: 4.15.0-24, previous 4.13.0-45 and -43.

If this is the wrong place to post this, please let me know where it should be posted. I have 3 posts in a row now on these forums that have gone unanswered in the past few weeks (and yes, I only posted after considerable searching for the answers on my own).

Edit with new info: I'm also unable to see a right-click menu from Linphone when it's minimized to the notification bar (next to the clock).

HI "kentchristopher",

See this recent post - Can't click menu items in several programs - KDE 18.3 - Linux Mint Forums
viewtopic.php?f=47&t=272789

Using the QtCurve Window Decoration will resolve this for most applications, supposedly, but it did not with Firefox for me. You may need to restart after this, or at least logout and log back in.

I tried changing Linux Kernels as well and that did not make a difference with this.

Whatever it is that caused this, I hope they fix it soon because this is something new.

Hope this helps ...

Thank you, I'll jump in on the thread you linked as it definitely seems to be the same problem.

Hi entchristopher,

You are welcome...

FYI: I tried the "Audacity" audio editor and the "DeadBeef' music apps and they are working for me using the 'QtCurve"...
