Qbittorrent looking weird after upgrade to Kubuntu 23.10

Here is qbittorrent on 22.04

And here is qbittorrent on 23.10

I tried going back to the qbittorrent version 4.4.1 (the one that shipped with with 22.04) and it looks equally weird on the new system

Any ideas?

The new one is the Qt6 version of Qbittorrent, and you’re missing the Qt6 version of whatever theme you were applying to the app.

You’ll most likely need to upgrade to Plasma 6 to fix this–once your distro offers it as an option.

Thanks for the succinct reply
