[SOLVED] Qt icons no longer showing after upgrade

I have previously followed the instructions to use qt5ct to configure Qt5 applications outside KDE to ensure that icons are shown correctly. However, after upgrading a large number of packages today, icons across Qt applications (Dolphin, Okular etc.) have suddenly disappeared. Running in the terminal reveals the following error message, repeated numerous times:

QPixmap::scaled: Pixmap is a null pixmap

Beyond this, I cannot track down the cause of this problem. qt5ct appears to run without errors, and QT_QPA_PLATFORMTHEME is still set to qt5ct. Does anyone have any ideas?

Ah-ha… with qt6ct it works, thanks! I really don’t know how I missed that.

Apologies, didn’t realise that was expected; have done so now.
