            Bug ID: 127131
           Summary: CPU to 100% when LibreOffice Calc is idle and has a
                    Calc-document open...
           Product: LibreOffice
           Version: 6.3.0.2 rc
          Hardware: Other
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
I've noticed this on 3 different computers, but all Linux-related (Xubuntu
18.04 LTS and Manjaro 18.0.4, Xfce): When I open a Calc-document (no different
if it's an existing document or a new Calc file), and I leave it idle for a
couple of minutes, the CPU starts to rise up to 100%. CPU drops to normal again
when I close Calc.

This behaviour is seen only in Calc, but not on the other components of
LibreOffice. This happens in LibreOffice 6.2.5.2 and LibreOffice 6.3.0.2, both
on x86 and x86_64 machines. OpenGL is disabled.

Steps to Reproduce:
1. Start LibreOffice Calc
2. Open or create a Calc document
3. Leave it idle for a couple of minutes

Actual Results:
CPU starts to rise to 100% and the computer heats up.

Expected Results:
Basically nothing particular...


Reproducible: Always


User Profile Reset: Yes
