I can reproduce this in NeoChat when clicking and dragging the chat history, but not MuseScore, which uses QML for its interface. Therefor, I think it's not QML-specific, but caused by Kirigami.

Adding the x11-only keyword
Comment 4 Marco Martin 2025-04-04 14:28:17 UTC 
This depended on some qt issues and was reported under Qt5.

Closing as is not really useful anymore.
if similar things happen with qt6, it should probably be reported and tracked upstream
