Bug ID: 159999
Summary: System process uses too much CPU on idle
Product: LibreOffice
Version: 24.2.1.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
Whenever I start Libreoffice, even without opening any file (it does not matter
if it is Writer, Calc ... etc) the "System" process shows a high CPU usage ,
even if Libreoffice is just sitting in the welcome screen doing nothing.
Right when I close LIbreoffice, the "System" process drops to 0-1 %
I want to emphasize that the RAM usage is at around 50%, so it is not Windows
dealing with the swapping/pagefile.
I have tried:
* Playing around by disabling Skia, hardware acceleration ...
* Updating the drivers
* Formatting my laptop
But the bug persists anyway.
My specs:
- Windows 10 22H2 x64 fully updated
- 8GB of RAM
- Intel Core i7-1165G7
- 256 GB SSD
Steps to Reproduce:
1. Start Libreoffice
2. Wait a while and the laptop/PC fan will ramp up !
Actual Results:
Open Windows's task manager, to see the "System" process with a high CPU.
Expected Results:
The System process should not have a high CPU usage.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
Version: 24.2.1.2 (X86_64) / LibreOffice Community
Build ID: db4def46b0453cc22e2d0305797cf981b68ef5ac

NB: I experienced this bug both with the x86 and the x64 versions of
Libreoffice.
