Description: Libreoffice Calc regularly/randomly hangs on macOS mojave and has to be force-quit, recovered and data re-entered. Steps to Reproduce: Open a new calc spreadsheet. Copy and paste URLs from chrome address bar into various cells (no idea if chrome or copy/paste has anything to do with it). After a few copy and pastes LO/Calc hangs (spinning wheel). Can leave it for 30 minutes and it is still the spinning beachball of death. Eventually have to "force quit" and start/recover documents. I get the apple error reporter but no libreoffice error reporter because it is a hang and so I guess the LO crash reporter also can't come up before the force quit from macos side. Sometimes just right clicking on a cell causes the hang (was trying to test mouse paste vs keyboard paste). Didn't get to paste, just the mouseclick caused hang. Paste unformatted doesn't make a difference. Restarted in safe mode and created a new Calc document... I could still reproduce in safe mode. I did not reset my profile because the docs (https://wiki.documentfoundation.org/UserProfile#Help_wizard_.28LibreOffice_5.3_and_newer.29) say if the problem is reproducible in safe-mode that the user profile is not the problem. Problem is also present on 7.3.X. I just downgraded to 7.2 hoping the problem would go away. Hardware acceleration is disabled. Skia is disabled (in the 7.3 version that had the issue). macos Mojave 2012 Macbook pro external monitor via thunderbolt 2 dock No clipboard management apps. I can't reproduce this in predictable steps because it isn't clear exactly what is triggering the hang. ...but it is happening often enough that I can't use Calc anymore because the hangs are frequent enough I have to constantly force-quit/recover and re-enter data lost since the last autosave. I suspect it is some hardware/rendering bug specific to my hardware or macOS version. I used Libreoffice for a long time with this hardware setup and it was rock solid (no crashes/hangs). This has only become a problem in the last few months I guess. I guess next step could be to downgrade minor version by minor version until the problem goes away so we at least know which commit-set introduced this. Actual Results: Libreoffice calc hangs regularly during mouse or clipboard interaction and has to be force quit. Expected Results: Calc should not hang Reproducible: Always User Profile Reset: Yes Additional Info: Happy to provide system/hardware report but not sure what format you might want that in. I can also provide the crash dump text that apple generates after the force quit.

Maybe a dup of https://bugs.documentfoundation.org/show_bug.cgi?id=148265
The freeze happens regularly but not through predictable steps. Sometimes on copy, sometimes just on mouse interaction. But it happens a LOT.... so if you can give me some input on how to collect some more data that might help you track this down I'm happy to do that. But I would need some input/instruction on what will help.

This is still a regular issue. When using libreoffice I have gotten in the habit of hitting cmd-s every 10 seconds or so to minimize loss of work. Happens at work and at home (both cases with thunderbolt 2 dock and external monitors, but not sure if that is relevant). I'm happy to work with someone from the Libreoffice team to repro this and capture additional data that will help to pinpoint the cause of the hang. Meanwhile I've had to subscribe to Microsoft office and get used to using Excel after 10 years without (I hate their interface). Don't want to, but this regular hang and data loss issue gets in the way of work. Anyway, just a reminder I'm happy to invest time on this bug with the right person from the Libreoffice team to get this resolved. Still present in 7.3.5.2 probably latest alpha too, but I didn't check again.
I experience this behaviour as well, but already in version 7.2 : in the middle of an edition, the application freezes. As this seems rather random, it is hard to tackle. My impression is that a click or mouse event (drag-drop) too close in time to a previous one is causing this, and that it is not only related to calc. I attach two sampling files of LO while hanging taken a couple of seconds apart (they are probably very similar). One can clearly see a mutex hanging there... Best regards, Vincent Boudry.

For what it's worth, this doesn't just happen on mouse/keyboard interaction. Often just opening a spreadsheet file is enough to hang at opening. I have to force-quit and then usually tell it to delete locks/recovery-data and try again. It has gotten so bad that I've abandoned LibreOffice because it happens so frequently. I will be very happy to start using LibreOffice again once this bug is fixed. I ran LO on Mojave for a long time without issue, so this bug was introduced at some point. I'm stuck on Mojave (for now) due to needing support for some legacy 32 bit apps. Maybe if I get some time I will step through old versions and try and figure out what build introduced this in the hope that more specific information will be enough for the team to address this. If someone from the dev teams wants to repro/debug this with me, I'm happy to get on a screenshare session and do what needs to be done to track down the root cause. I'm a webapp guy and don't have that much experience debugging native apps or LO in particular.

FWIW, I'm not able to reproduce this in: Version: 7.4.0.2 / LibreOffice Community Build ID: 1512ce97d7ed39dce3121f7e15651fd8895f950e CPU threads: 10; OS: Mac OS X 12.5; UI render: default; VCL: osx Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded @MattP, if you are comfortable with using git, then the best way you can help debug this is to try and bibisect it to a range of commits or even a single commit. You can find instructions for this here: https://wiki.documentfoundation.org/QA/Bibisect
