Description Riccardo Robecchi 2025-03-11 10:11:54 UTC 
SUMMARY
Open/save dialogues are opened on a different monitor from that of the parent window on X11. This is very annoying and frustrating. This seems to only happen with KDE/Plasma dialogues of non-Qt-native applications; as an example, this happens with Slack and Vivaldi which use the KDE/Plasma dialogue although they are not Qt-native applications. GTK dialogues are opened correctly on the monitor where the parent window is.

STEPS TO REPRODUCE
1. Invoke an open/save dialogue from a non-Qt-native application (e.g. in Slack)

OBSERVED RESULT
The dialogue does not open on the same monitor.

EXPECTED RESULT
The dialogue opens on the same monitor.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE Neon
KDE Plasma Version: 6.3.2
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2

I assume this is a regression of some sort? Do you remember when it last worked?

Comment 3 Riccardo Robecchi 2025-03-11 23:24:32 UTC 
I updated straight from Plasma 5.27.10, so that is my only reference - it worked back then, though I realise that is not a great point of reference!
