Created attachment 174721 [details] Can't drag'n'drop in dolphin SUMMARY Unable to drag'n'drop in dolphin. This was working, dolphin has not been upgraded, but I did update to plasma 6.2 and then this broke. I'm also seeing other drag'n'drop issues in plasma panels eg https://bugs.kde.org/show_bug.cgi?id=494520 and I just noticed it's also effecting the launcher so I'll file that next) that came with that upgrade. I would guess that this is actually a kwin bug? But filing it against dolphin as that's where I'm seeing it. Video attached. STEPS TO REPRODUCE 1. Update to plasma 6.2 2. Try to drag'n'drop files in dolphin OBSERVED RESULT Cursor turns into the red circle+white X cursor when starting to drag, and dropping the file does nothing EXPECTED RESULT Drag'n'drop with the optional cool menu at the end (BTW, geez, that feature is SO nice, a11y/10, thanks!) like usual. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20241009 KDE Plasma Version: 6.2.0 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.3 Kernel Version: 6.11.2-1-default (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3090/PCIe/SSE2 Manufacturer: ASUS
Unable to reproduce in Qt 6.8. It's expected that the cursor turns into the red circle initially, because you can't drop the file onto other files. But when I drag it into the empty area below files, the cursor turns into a plus sign. Also, the filename should be under the cursor when dragging, but it's missing in your screen recording. So it seems there is something wrong in your DnD, but I'm unsure what it is. Maybe a Qt 6.7.3 specific problem.

(In reply to Jin Liu from comment #1) Hi Jin Liu, thanks for looking at this for me > Maybe a Qt 6.7.3 specific problem. That seems plausible. I'm certain it's not specific to dolphin as I've seen the same kind of broken DnD in other KDE apps (see also). I'm using openSUSE tumbleweed, and I don't seem to be able to find even a pre-release package of qt 6.8 to try. Is there anything else that I could do, to try and pin this down? Happy to spend as much time on it as needed.

Happy to spend as much time on it as needed. I'll try downgrading to Qt 6.7.3 to check this.
Can't reproduce with Qt 6.7.3 in Arch. Maybe you could report this to opensuse.

No response from them at all, is there anything else I could try? Maybe something I could enable, to obtain logs of this behaviour?
Fixed by forcibly reinstalling Qt6 (494520 for details) Thank you very much for your help :)
