Bug ID: 100109
Summary: Memory leak and high CPU use when scrolling a file in
writer
Product: LibreOffice
Version: 5.1.2.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer

problematic file
LibO freezes my PC when trying to scroll on the attached file. It contains
several formulas which aren't displayed properly. I can reproduce this bug
every time with this specific file under LibO 5.1.2.2 (version by default in
Kubuntu 16.04):
Versión: 5.1.2.2
Id. de compilación: 1:5.1.2-0ubuntu1
Hilos de CPU: 3; Versión de SO: Linux 4.4; Renderizado de IU: predeterminado;
Configuración regional: es-AR (es_AR.UTF-8)
However, I *can't* reproduce it under LibO 5.0.6.3 (downloaded from
libreoffice.org)
Versión: 5.0.6.3
Id. de compilación: 490fc03b25318460cfc54456516ea2519c11d1aa
Configuración regional: es-AR (es_AR.UTF-8)
This was tasted under a clean prefix.
Steps to reproduce:
1) Open the attached file with LibO 5.1
2) The first thing I noted is that several equations are not shown in Writer
5.1 (but they are actually shown in 5.0. This could be a separate bug or even
related).
3) Start to scroll down using the mouse wheel.
Results
1) After certain time, Writer 5.1 uses all CPU and a lot of RAM (~3GB), having
to kill it from a TTY since the all the UI is freezed.
Expected
1) No memory leak nor high CPU use, as in LibO 5.0
This bug could be related to bug 87485 and bug 61558. However, those bugs were
reported for LibO versions prior to 5.0, in which I can't reproduce this
specific bug. Also, I have experienced this very same bug under different
circumstances, but haven't been able to reproduce it precisely.
