I can't reproduce it in

Version: 6.4.0.0.alpha0+
Build ID: cc65651a0490383f1a833bb6215d8ec4272d8b5d

To be certain the reported issue is not
related to corruption in the user profile, could you please reset your
Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and
re-test?

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the issue is still present

I found more information: the bug only happens when libreoffice-qt5 is installed (and I'm in a Plasma desktop, so the Qt5 integration gets activated)

BTW the bug still happens after an upgrade to libreoffice-calc-6.2.7.1

This isn't user profile corruption, the bug also happened on my wife's computer (different user profile, same OpenSuSE version).

Hi David,

this reminds me a bit of bug 124356, so can you please retest with LibreOffice 6.3, or even a master daily build as available at [1], which can be installed in parallel as described at [2]?

If the issue is still present there, can you paste the exact info from "Help" -> "About LibreOffice"?

I cannot reproduce with current master, neither with the "kf5" nor the "qt5" VCL plugin. (Those two are different, and I *think* and hope that the "libreoffice-qt5" package from OpenSUSE actually includes "kf5", not just "qt5", since the latter is definitely not meant for production as of now.)

Can't reproduce with:

Very confusing: today, still with 6.2.7.1, I can't reproduce the problem either.
I don't understand what changed meanwhile, or whether there's another subtle trigger for the bug which makes a difference.

For information, the libreoffice-qt5 package for opensuse contains both plugins:
/usr/lib64/libreoffice/program/libvclplug_kde5lo.so
/usr/lib64/libreoffice/program/libvclplug_qt5lo.so
(as well as libkde5be1lo.so)

I assume the first one is the one you called kf5?
Is there any way to see which one is actually being used?
Thanks.

Thanks for the update. Should we close this as WORKSFORME then?

Yes, it's called kde5 in LibreOffice 6.2 still, but has been renamed to kf5 for later versions to fit KDE community's wording (s. bug 125922 for details).

> Is there any way to see which one is actually being used?

Yes, that's shown in "Help" -> "About LibreOffice" (which is why I was asking), and you can request to use a certain VCL plugin by setting env variable SAL_USE_VCLPLUGIN (to "kde5"/"kf5", "qt5", "gtk3", "gen", ...) on startup.

And today it happened again. Still with the same version of everything.

To find out more, I took good note of which document this was happening in, closed all LibreOffice windows, checked the soffice process wasn't running anymore, reopened that same document ---> the bug doesn't happen anymore.

So there's an additional trigger somewhere which I have still to find.
It's definitely not related on the document contents, when it happens, it happens on all spreadsheets. But there's some other action that has to happen first, before the bug actually happens. Could be suspend-to-ram, could be opening more docs from the command line, could be the file dialog... but I just tried all of these things, and the bug still isn't back. So it's something else.

It would be useful if someone who knows the source code could tell me what might possibly lead to this. How can the qt5/kf5 integration possibly affect what happens when the window receives focus? QFocusEvent handling surely. But why would this ever start editing the cell?

I don't have a quick idea on what might be causing this. The qt5 and kf5 related code is in [1] and [2].

[2] https://gerrit.libreoffice.org/plugins/gitiles/core/+/master/vcl/unx/kf5/

@QA: the Qt5 meta bug is only for QPainter based problems (which are basically currently ignored, due to the more important kf5 based bugs). Everything else Qt5 and KF5 related should be handled via the KDE metabug. Please always request a copy of "About LibreOffice", if you think it's a platform problem, so the reporter and us can make sure the problem is attributed to the correct VCL backend. The dialog text is selectable, so easy to copy into the bug report.

Nothing else from my side to add to this problem :-(

"About LibreOffice" says:

Version: 6.2.7.1
Build ID: 20(Build:1)
CPU threads: 8; OS: Linux 4.12; UI render: default; VCL: kde5; 
Locale: fr-FR (en_US.UTF-8); UI-Language: en-US

IMHO, it'd really be interesting to know whether the issue still happens with LibreOffice >= 6.3, or whether this is possibly the same thing as bug 124356 (s. comment 3) that seems fixed there.
