> I cannot reproduce.

Hmm, pretty sure there is something bug 120727 comment 39 has the same experience.
Based on the BT I would say its bit of a timing problem: SkiaFlushIdle

    frame #6: 0x0000000104d5e0e7 libvcllo.dylib`SkiaSalGraphicsImpl::performFlush() + 215
    frame #7: 0x0000000104d71442 libvcllo.dylib`SkiaFlushIdle::Invoke() + 18
    frame #8: 0x0000000104b85765 libvcllo.dylib`Scheduler::CallbackTaskScheduling() + 4773
    frame #9: 0x0000000106d36197 libvclplug_osxlo.dylib`AquaSalTimer::callTimerCallback() 

Another speculative one:
1. Open Writer
2. Open second Window
3. Go the first LibreOffice -> About -> press copy about button
4. Go to the second window & paste
5. Go again LibreOffice -> About -> press copy button (freeze)


@Steve
Any luck to reproducing this? Is bit of an erratic crash :-(
Comment 4 Telesto 2021-12-01 07:57:25 UTC
1. Open LibreOffice (Start Center)
2. Writer document
3. Help -> Restart in safe mode
4. Cancel
5. LibreOffice About. Press copy button
6. Close dialog
7. LibreOffice About. Press copy button
8. Help -> Restart in safe mode
9. Switch to different app and back
10. Cancel dialog
11. LibreOffice About. Press copy button

Crash should occur somewhere in this dance. Sometimes it crashes instant, other times it takes a little longer
Comment 5 steve 2021-12-01 13:42:36 UTC
Unable to reproduce.

Unsure about step "8. Help -> Restart in safe mode", are you actually restarting?  Since previously you specify "cancel" but don't indicate how to proceed this time around.

But then again I am not sure how to switch to "Skia/Raster". I see "Skia/Metal" in about. So I might be holding it wrong (TM)?

Well Metal won't crash... Needs to be Raster: LibreOffice -> Preferences - View -> Force Skia Raster

Regarding to the dance. No I didn't press Restart in safe-mode.. It has something to do with dialogs causing a crash out of the sudden. I have narrowed it down (but it isn't exact on timing). It does crash within the minute toying around with about/safe-mode dialog (so on my system regularly)

And well, I forgot, thanks for testing..
Comment 8 Telesto 2021-12-01 15:50:22 UTC
Straight forward crasher:
1. Open soffice (so start center)
2. Click Impress (assuming the wizard enabled)
3. Double click on the slides panel (with wizard still on top) -> crash

Comment 9 steve 2021-12-01 22:42:40 UTC
Haha, now I ran into a crash while trying to find Skia Raster 😂

I assume this is the same crash since as you correctly state it is related to having some dialog open.

Crash log (1 year): https://bin.disroot.org/?c61ed6e4f58e2301#Bc7jqwpvTJKUUtV76StxSNMLjXyDWkqzNtLbMBjXDN8B

Setting to NEW since I at least once reproduced the crash in question. Could you double check if you note anything from the crash log that matches / confirms it is the "correct" crash we are looking for.

Took another look at Preferences > View > and there is no info about Skia Raster (also LO just instantly crashed as soon as I opened the preferences window).

I have two Skia settings:
Use Skia for all rendering
    Force Skia software rendering

That's it. No raster anywhere in sight.
Comment 10 Telesto 2021-12-02 11:02:18 UTC
(In reply to steve from comment #9)
> Haha, now I ran into a crash while trying to find Skia Raster 😂

Well Skia Raster = Force software rendering; the about screen will show "Skia Raster" if Force software rendering being abled

I personally find this confusing too, but and complained; see bug 144330 (rejected)

Only for my informaton: You're testing on own build or against the pre-published? [Not sure if the build bot is running some different version of Xcode or something like that] 
And which macOS version?
Comment 13 Telesto 2021-12-12 08:25:13 UTC
FWIW. I wanted to setup lode for a build with symbols for the crash, but lode is refusing to install
 lode % ./setup
Unknown Darwin kernel version 21.1.0 (macOS Moneterey)

Few side notes
A)Baseline starting to be ambitious to formally support. 
B)It might be that  the difference between build and runtime environment also starting to cause issues; no clue.

Double checking, as comment 0 isn't mentioning Skia Raster as explicit requirement (it is) and the about here showing Vulkan..
Comment 16 Telesto 2022-01-24 10:24:22 UTC
Finally got LODE setup. My custom build is running fine.  So this or a problem with code signing (I think it's not). Or something with the baseline version used to build LibreOffice.

Will try a more recent Master build soon, to check if it's still present..

A) The problem appears to be limited to macOS Monterey (all reports pointing into that direction)

B) It only occurs with Skia Raster mode (aka Software rendering). Tools  -> Options -> View -> Force Skia Software rendering. 

C) It only occurs with Master builds (not self-build)

D) It might be dependent on Haswell processor

I was able to reproduce this bug with Skia/Raster. Unfortunately I was only able to reproduce one time. That was on my macOS Intel running macOS Monterey 12.6.2.

I am testing by running a local build (checked out from master earlier today) in lldb. Does anyone have any other steps that they use to trigger this crash?

Whole problem, I can create the issue with a few steps.. somehow, but not everybody else does. 

Comment 8 works pretty reliable for me

Alternative
1. Open Impress from Start Center
2. Double click BeeHive template
3. LibreOffice -> About Window -> Press Copy About
4. Close the dialog
5. Enter Click to add title
6. CMD+V
7. LibreOffice -> About Window -> Press Copy about -> Might crash here
8. Close the dialog
9. Go to slide 2
10. CMD+V
11. LibreOffice -> About Window -> Press Copy about -> Crash

Alternative -> even less predictable
1. Open Writer from Start Center
2. LibreOffice -> Preferences -> View
3. Uncheck Use Skia for all rendering
4. Hoover over the Apply/ OK buttons.. Press Apply button. Close the restart button. Press Cancel in the Preference dialog 

It appears Window related, the dialogs appear like tip of the day/ template manager/ about window/ preference the often it happens.

But will there some kind of timing element.. 

Sidenote: the patch attachment 181096 [details] authored by Luboš Luňák - received by email - solves the issue. However a different patch got pushed at comment 24 for unknown reasons

Thank you for the steps. I can now reproduce the crash using your first alternative.

I now understand why the patch in attachment 181096 [details] was not used: it makes a copy of the bitmap in memory. It fixes the crashing, but it would require a lot more memory and frequently copying of bitmaps.

I added the debug patch in attachment 184138 [details] and I noticed the following debug output immediately before the crash:

debug:2178:56744: XXX:0x600003e71e00 709x464*2R::1418x928::2::244x232@(399,156) 798,312,488,464::5672::6 2::6 2
debug:2178:56744: XXX:0x600003e71e00 709x464*2R::1418x928::2::200x145@(509,319) 1018,638,400,290::5672::6 2::6 22022-12-14 08:57:10.358900-0500 soffice[2178:56744] [org.libreoffice.script] copy_read_only: vm_copy failed: status 1.

Note that the first line doesn't crash and the second one crashes. Both are taking a small subarea of the same bitmap. The difference is that the subarea in the second one aligns with the bottom, right edges of the bitmap.

From the above, I think that Luboš Luňák's "HACK for tdf#145843" in vcl/skia/osx/gdiimpl.cxx now makes sense to me. His fix is just missing cases like this.

I will see if I am able to expand his fix to handle this case.

Ignore the above patch. CGBitmapContextCreateWithData() crashes as well just not as frequently as CGBitmapContextCreate().
