I have LO installed on my laptop with Archlinux. I'm not sure if it is one single bug or more or any. :]
I started LO from command line. Performance issues occurred when I try to save file to XLSX with longer name with space.
Steps to Reproduce:
1. Open XLSX file from command line. This message is shown sometimes (I don't see any rule for appearing):
$ loffice /tmp/file.xlsx
(soffice:12898): GLib-GObject-WARNING **: 15:15:58.795: ../glib/gobject/gsignal.c:3492: signal name 'selection_changed' is invalid for instance '0x563d9fc98ea0' of type 'OOoAtkObjCompTxt'
2. Work with. Trying to save as XLSX with some long name, i.e. "abcd efgh ijklmn opqrs tuvwxyz.xlsx" and then LO get stuck (it's not possible to work with LO at all). In htop I see these 2 processes which every eats 100% of CPU:
/usr/lib/libreoffice/program/soffice.bin /tmp/file.xlsx --splash-pipe=5
3. I have to kill it in KDE (pressing ctrl+alt+escp).
4. After killing LO window I see in htop "lo_kde5filepicker" processes which consumes 100% of CPU.
LO gets stuck and CPU is overloaded.
Normal run of LO without overloaded CPUs.
User Profile Reset: Yes
OpenGL enabled: Yes
After restarting in Save mode this bug didn't occurred but in command line I see this output:
loffice --safe-mode /tmp/file.xlsx
kf5.kio.core: Invalid URL: QUrl("abbcd efgh ijklmn opqrst uvwxyz.xlsx")
