To Reproduce
Happens when dragging a JTabFrame tab to another location.

Additional Information:

• OS: Manjaro
• Darklaf Version: 2.6.1

Is this within a single application or between different applications? Otherwise I'm not sure why serializing the 'TabTransferData' is even attempted.

[GraxCode]

I don't know, but i assume it is not within a single one.

It seems like this happens when dragging the tab outside of the frame onto the desktop. I am on Manjaro KDE.

Thanks for the info. I'll investigate how to rule out the desktop as a drop target then. It really doesn't make much sense to drop a UI component on the desktop :D.
