Oh wow, can reproduce. I wonder how I never noticed this before.

Qt bug with ongoing fix upstream: https://bugreports.qt.io/browse/QTBUG-127821
(In reply to Niccolò Venerandi from comment #5) > Qt bug with ongoing fix upstream: > https://bugreports.qt.io/browse/QTBUG-127821 Nice! Thanks for your help with this and letting us know.

I heard rumour elsewhere, that this patch is intended to fix this issue: https://codereview.qt-project.org/c/qt/qtwayland/+/565408 If there's any validity to that rumour, I'd be interested to try it out?
It's actually https://codereview.qt-project.org/c/qt/qtwayland/+/581714
(In reply to Nate Graham from comment #9) > It's actually https://codereview.qt-project.org/c/qt/qtwayland/+/581714 Thanks Nate! Works great here, can confirm that patch resolves this issue at my machine. I'd normally like to help out my distro by packaging a cherry-picked patch like this, but it seems like it might be too soon for me to go ahead yet(?). I'll keep an eye on that link for when it is approved at that end, but if you feel like it's safe to go ahead and patch distro packages, let me know. Thanks again and have a good weekend :)

FYI the above patch is no longer functional in 6.2 - with or without it, Task Manager entries can not be moved at all. I'll file a separate bug for that, but I wonder if maybe the Icons-and-Text Task Manger is missing from some tests?
I forgot to remove the patch and had the same issue, which also affected moving files in dolphin as well. Removed the patch and recompiled dev-qt/qtwayland (gentoo), rebooted and the issue went away.

(In reply to saunders from comment #14) > I forgot to remove the patch and had the same issue, Removed the patch and recompiled dev-qt/qtwayland (gentoo), rebooted and the issue went away. So, plasma 6.2 fixed this bug for you, even without the qt fix above? For me, the qt patch was added to the distro's stock qt6-wayland package, so I removed my modified package and that installed the distro's stock package in its place. The original problem persists, as does the new one. > which also affected moving files in dolphin as well. This sounds like a different bug.
(In reply to pallaswept from comment #16) > (In reply to saunders from comment #14) > > which also affected moving files in dolphin as well. > > This sounds like a different bug. Apologies, I misunderstood. I thought that you meant that you saw this dolphin bug with the previously reported bug. In fact, it's a new behaviour. I've just come across it, myself, with 6.2. Like the drag'n'drop bug, for me at least, it persists with or without the qt patch from this bug. If you've found a workaround, I'd love to hear any details you could share. I assume you already filed a bugzilla for the dolphin bug? I couldn't find it, so I went ahead and filed one. https://bugs.kde.org/show_bug.cgi?id=494581. The same behaviour also appears in the launcher: https://bugs.kde.org/show_bug.cgi?id=494582 I guess, since this appeared with a kwin update and without a qt update or application updates, this is an unrelated kwin 6.2 bug, which is masking this original bug - but you've reported that you solved it by rebuilding qt, but qt doesn't have the patch, so....I don't get it?
The fix has been merged for Qt 6.9.0. Now let's see if we can get it backported to 6.8 as well...
For to 6.8 (cherry picked): https://codereview.qt-project.org/c/qt/qtwayland/+/599253
Looks like it's in 6.8.1, I just got it on Tumbleweed, they aren't patching the source at all, so I guess everyone will get it. Thanks heaps for your help everyone!
Seems like this is still happening with QT 6.8.1 and I can also reproduce it.

(In reply to David Redondo from comment #21) > Seems like this is still happening with QT 6.8.1 and I can also reproduce it. I notice from the bug you just linked that the reporter is running the 6.3 beta and KF 6.11. This is the current Tumbleweed (just updated to be sure): > kinfo Operating System: openSUSE Tumbleweed 20250128 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.1 Kernel Version: 6.13.0-1-default (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 31.2 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3090/PCIe/SSE2 This bug doesn't exist on the above system.
I am running 6.8.1 and git master FWIW and have the issue
I can also still reproduce it with Qt 6.8.1.
(In reply to Nate Graham from comment #25) > I can also still reproduce it with Qt 6.8.1. I don't mean to argue, but just to help to pin this down, I'm certain this is more 'again' than 'still'. It's definitely fixed in Qt 6.8.1, on plasma 6.2.5. So it seems that maybe something changed on the plasma side (or maybe it's frameworks, assuming you're also on KF 6.11?) If you need a testbed for this I'm happy to offer my machine.
I've heard that 6.3 is due to be released shortly, is there anything I can do to prevent the release having this bug?
I think I observed the following: It goes wrong when the cursor does not leave the panel. when I move the cursor out of it and back in again dragging works as it should
actually I observed wrong
This commit fixes it fully for me https://codereview.qt-project.org/c/qt/qtwayland/+/623667
This bug has also reappeared for me after upgrading to Plasma 6.3.0 on Fedora 41 (using the testing repo, but the update has been submitted for stable already), after it had been fixed in Qt version 6.8.1.

Thanks David! Once that's merged, we can ask distros to backport it.
I have just installed tonight's daily updates from a COPR I use and it is indeed fixed. Thanks! Operating System: Fedora Linux 41 KDE Plasma Version: 6.3.80 KDE Frameworks Version: 6.12.0 Qt Version: 6.9.0 Kernel Version: 6.13.3-200.fc41.x86_64 (64-bit) Graphics Platform: Wayland
That's great news! Thanks for the confirmation.

(In reply to Nate Graham from comment #37) > *** Bug 497119 has been marked as a duplicate of this bug. *** Hi, Could you describe me how to apply the patch exactly? Or else could you give me a link to a ressource or something that explain it in details? Because when I tried while awaiting for the Qt 6.8.3 update, it just told me I already had the patch and I tried to un-apply it like it suggested, and then re-applied it, but it still don't works sadly :/ Thanks in advance!
I don't have that information, sorry. Someone else will need to help you with that.

Just tried qt 6.8.2 in Debian (testing pulled from unstable) with Plasma 6.3.2 and this bug still happens. Should I ping Debian developers to backport this patch? https://codereview.qt-project.org/c/qt/qtwayland/+/623667

I also can confirm https://codereview.qt-project.org/c/qt/qtwayland/+/623667 also fixes things for me again after the bug reappeared). So glad to see this finally fixed!
Debian developers uploaded the patch and manually rebuilding qt6-wayland indeed fixes it! https://salsa.debian.org/qt-kde-team/qt6/qt6-wayland/-/blob/master/debian/patches/use_same_pointing_device.diff?ref_type=heads Hopefully new qt6-wayland packages will be uploaded to Debian repos soon.
