I can confirm that problem is solved and everything works well on Arch based systems since some time.

Problem is fixed since a while so the thread can be closed.

I assume, this will land in arch automatically after some time?

Have you compiled the package with the fix and tried it out?

Thanks, I really appreciate you working on it. From some weird reason vlc doesn't work well on my main computer, other players cannot show correctly UTF-8, polish subtitles so the only player (and a good one) that can do everything and also is (or was) nicely intergrated with Plasma is SMPlayer. So literally, I have no options. SMPlayer is the only solution for me. As to the assumption that the fix may already exist, that's possible. Lxqt c1 session fix needed at least 1-2 months till it arrived...

Even if it tunrs out not to be a KDE bug, it's worth a try. Maybe you will get to bottom of it. It's possible KDE changed something deliberatelly and you only need to adjust to it. Also, why only SMPlayer is touched with the issue? No other app seems to have similar problem. So either SMPlayer does something unique that does uncover some lib bug, or the bug is in SMPlayer.

If KDE libs may be the probable cause, can someone file a bug? I would gladly do that (and I did that in the past when I knew more) if I understood what you are talking about.

If fix is not quick to find, this seems to be a reasonable course of action. At least smplayer will work automatically for people. However, probably we will see some growth of topic like "smplayer doesn't have kde global menus" etc.
