Bug ID: 496243
Summary: Wrong mouse cursor is used for some Java Swing
Drag-and-Drop operations
Classification: I don't know
Product: kde
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Screenshot of the bug
SUMMARY
When performing a drag-and-drop operation originating from a Java Swing
application, the mouse cursor is constantly shown as the Not Available cursor,
even if the application indicates that the drag is possible and the normal Move
cursor should be used, see screenshot.
I tried switching to Gnome on Wayland and Plasma on X11 and both of these made
the bug go away, the incorrect cursor displays only in Plasma on Wayland.
STEPS TO REPRODUCE
1. Launch any Java Swing app that support drag-and-drop. The DnD demo
application at
https://docs.oracle.com/javase/tutorial/uiswing/dnd/basicdemo.html works for
this purpose, I also tested with other apps.
2. Attempt to drag a drag-able item from the application
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Linux 41
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
ADDITIONAL INFORMATION
openjdk 17.0.13 2024-10-15
OpenJDK Runtime Environment (Red_Hat-17.0.13.0.11-1) (build 17.0.13+11)
OpenJDK 64-Bit Server VM (Red_Hat-17.0.13.0.11-1) (build 17.0.13+11, mixed
mode, sharing)
I'm guessing this is a bug in kwin, but I'm not completely certain. This is my
first time filing a bug with KDE, I apologize if I did something wrong.
