There were lots of dnd improvements in 5.23. On my machine, dnd works, the file is uploaded successfully.

The file disappears though after dropping and re-appears after a click. That's most likely due to Qt not supporting the latest wl_seat.

Yeah, works for me too in 5.23. \o/

Comment 3 Ivan Mercep 2021-10-07 18:20:30 UTC

Please fix the disappearing after drag and drop.

Can confirm, but can you please file a separate bug report to track that? Thanks!
