MacOS: Collabora Office: Random crashes when moving window via windows management

User Support

On MacOS, when moving the Collabora Office program window via an automated method it will sometimes crash and terminate.

I only use “Text Document” & “Spreadsheet” and didn’t test others parts of the app. It has previously done this for a couple years when I was using BetterSnapTool, but it is also doing it now using MacOS Sequoia’s built in window management (“Tile” & “Fill”; using Menu Option: Window > Move & Resize, the program window expand button’s long hold shortcut and dragging the window to screen edges). Sometimes I can move and resize the window without issue, sometimes it crashes immediately as it attempts to move/resize. I always thought it might be some compatability with how BetterSnapTool does things so I didn’t bother reporting it, but now that it’s doing it with native window management too…

It’s a fresh install of MacOS 18.0 on a 2023 MacBook Pro, Collabora Office is from the Mac App Store and is up to date (24.04.3.2 AARCH64). The MacBook Pro is in Clamshell mode with two external displays connected. System Setting “Displays have separate Spaces” is turned on (required for window management) and “Stage Manager” is turned off.

Annoyingly, auto-recovery also always fails when I re-open the app (the document shows in the list with the option to recover, but it always throws an error “Access to /Users/…/file.xlsx was denied.” when attempting to recover).

Anyone else having this issue, any thoughts, any way to report it as a bug?

This sounds like a bug that has been fixed a while ago in LibreOffice. I haven’t had this crash in a long time with LibreOffice.

I noticed I have the same version on my machine, including macOS 18, and don’t seem to have this issue. I do use Rectangle for window management, but disabling it I don’t seem to be able to reproduce what you write.

Unfortunately it’s not a consistent crash. I just now dragged a window back/forth several dozen times to try and find a way to replicate, and no crash, then thought maybe it’s a multiple file open thing and opened another file, no crash on a few drags then, bang!, crash, try the exact same procedure again and no crash, then several more drags, no crash.
Makes it hard to pin down something exact… (only happens with?:… external displays? multiple displays? multiple files? an unsaved file? files with certain features? who knows…)

But it has happened on this MBP’s fresh install (done mainly because of this issue), previous install after removing BetterSnapTool, previous install with BetterSnapTool, previous Intel MBP with BetterSnapTool, and with LibreOffice on the previous MBP as well…

The only thing I haven’t tested is using the MBP as a laptop rather than in clamshell mode (since I rarely use it in laptop mode).
