I can confirm it. Look at my last post in this seemingly unrelated bug: https://bugs.gentoo.org/910511#c10
Perhaps this is a regression in 5.15.10, unfortunately the previous ebuilds have already been dropped from portage, would have made it easier to rollback
Could you build all of dev-qt/* with debugging symbols (https://wiki.gentoo.org/wiki/Debugging#Per-package) (feel free to skip qtwebengine obviously) and give us a new bt, ideally with some precise reproduction instructions as I don't use sway?
https://bugs.kde.org/show_bug.cgi?id=472313 maybe. Also, darkdefender, did you have a bug like this where you posted a workaround patch on bugs.kde.org, or am I misremembering? (Was it a monitor issue instead?)
Do you mean the patch I posted in this report perhaps? https://bugs.kde.org/show_bug.cgi?id=470925
(In reply to Sebastian Parborg from comment #7) > Do you mean the patch I posted in this report perhaps? > https://bugs.kde.org/show_bug.cgi?id=470925 Yes, thank you!
I used that patch for a while seemingly without any issues. So we could perhaps patch qtgui on our side. But I would of course rather have upstream include it or fix it in other ways on their side.
applied upstream patch to qtgui did not fix the issue for me. rebuilding all of dev-qt/* use debug enabled ``` sudo USE=debug emerge -1av $(equery l dev-qt/* | cut -d' ' -f 2 | sed -E 's/^/=/') ``` will publish new `bt` when complete

Please see the link I sent and use that. USE=debug is for assertions and is unrelated.
ok thanks, sorry I missed that, as for the patch, it causes dolphin and qtfm to no longer crash, but drag and drop still appears to be broken. rebuilding again for proper `bt`
Please test this patch (apples fine over qtwayland-5.15.10: https://invent.kde.org/qt/qt/qtwayland/-/commit/22daca49b807fefba58113a06b86df4274e49f62

probably worth mentioning, drag and drop work without issue when you do QT_QPA_PLATFORM=egfs qtfm | dolphin
Thanks for testing. Regarding the remaining issue, do you have sys-apps/xdg-desktop-portal installed and FUSE enabled in kernel?

My qtwayland MR was already merged upstream. Can you describe in detail what's happening, now that it does not crash? "It's broken" is not sufficient for others to try and make sense of it.
(In reply to Andreas Sturmlechner from comment #21) > My qtwayland MR was already merged upstream. > > Can you describe in detail what's happening, now that it does not crash? > "It's broken" is not sufficient for others to try and make sense of it. Its described above already.. the test is to drag a file or folder in qtfm and dolphin, both do not allow icons to be picked up and dragged. it doesn't crash anymore however, icons cannot be dragged or carried by the mouse. This appears to effect all qt apps in wayland. if i switch the backend to xcb, I can drag files and folders with the mouse without issue.

You had described a test that I can't reproduce in my everyday usage of dolphin, we (and upstreams) need your observations that you provided just now.

Your saying drag and drop testing as described above works fine for you? your running in a wayland native DE? sway? let me know how you would like me to proceed in testing.

It works fine for me in Plasma Wayland, every day, now with that crash fixed as well. This bug is solved as far as the original reason of opening is concerned. The other phenomenon you see is not described by anyone else in here and upstream bugs, so it is another, but a different, bug. Maybe https://bugs.kde.org/show_bug.cgi?id=459605

Maybe > https://bugs.kde.org/show_bug.cgi?id=459605 Hmm, So.. 1. I filed this ticket :) 2. I said DnD broken in all QT apps under wayland not as KDE apps crash.. 3. The patch you applied in PR is different than the last one I tested in here, so I'll wait for it to sync, and cross my fingers that it fixes the issue. 4. for clarity this issue did not exist in the previous release of qtgui Would you prefer I re-open here if dragging issues persist? thanks!

For another crash with the same backtrace in newly fixed version you would re-open this bug. (In reply to Gino McCarty from comment #22) > both do not allow icons to be picked up and dragged. > [...] icons cannot be dragged or carried by the mouse. For the phenomenon you described for the first time properly in comment #22 you would open a new bug with as much as detailed description as possible for any future reader.
I confirm this bug has been frustrating me for few weeks now. Updated world last night and problem persists. I had previously applied a patch to qtgui, which stopped the crashing, but drag drop remained broken. Also affects GNS3 under wayland, running QT_QPA_PLATFORM=xcb allows normal drag drog. Here's my backtrace (running dolphin); Starting program: /usr/bin/dolphin [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".

This issue is in all qt apps, under wayland not just KDE. I think we won't get much traction here though, I suppose I can open another ticket that's basically a duplicate of this one. Nice to know I'm not the only person having this issue. :)
Clint, your backtrace is truncated. Please include the full output after running "bt". But it's not the same bug if it's not crashing for OP anymore.

Later i'll find the time to recompile qt and everything depending on dolphin to have another go. Confirming dolphin crashes for me, the instant I attempt to drag drop something. Running current testing @world.

(In reply to Gino McCarty from comment #33) > FYI qtwayland-5.15.10-r2 is ~amd64 not marked stable yet Exactly. Clint, make sure you have updated to that version, and drop your patch for qtgui (which one was that, btw?). Please note that you are talking about separate issues at the same time here, so make it absolutely clear in your statements if you are having a crash or seeing something else. That's why this should not be mixed in one single bug.

I removed #"${FILESDIR}/${P}-send-release-button-event-on-pointer-leave.patch" but left "${FILESDIR}/${PN}-5.15.9-fix-mouse-stuck-in-pressed-state-after-DnD.patch" and not drag and drop is working in both qtfm and dolphin
