Description: Calc periodically causes high CPU load (1 core @100%), even when its window was minified and there was no user interaction. Load goes away as soon as document is "Save"d again, even though there were no changes/edits since last saving. Steps to Reproduce: 1. Open attached Calc spreadsheet. It's fairly small, 700 rows by 2 columns, and around 20kBytes. 2.Minify the Calc window 3.Wait indefinitely ;-) 4 . On my machine, an 8 core Intel NUC, eventually the CPU fan revs up, and the xfce tas monitor indicates a 100% CPU load of one core, caused by LibreOffice, giving an average CPU load of between 12% and 13%. 5. Restoring the LibreOffice Calc window and hitting the "Save" button makes the CPU load go away, until the next time this happens. Which may be 30 (or more) minutes later. Actual Results: High CPU load, as shown in attached screenshot. Expected Results: If application is idle, like when window is minified and no user interaction taking place, it should remain at miniscule CPU load. Reproducible: Always User Profile Reset: Yes Additional Info: OS is Debian stable, fully updated as of today. Synaptic does not indicate any updatable packages, even after reloading the packages list from the download sources. LibreOffice version is as follows: Version: 6.1.5.2 Build-ID: 1:6.1.5-3+deb10u5 CPU-Threads: 8; BS: Linux 4.19; UI-Render: Standard; VCL: gtk2; Gebietsschema: de-CH (de_CH.UTF-8); Calc: group threaded After restarting LibreOffice in Safe Mode, pretty exactly 30 minutes later the CPU fan started revving up, with CPU load at 13% average, one core at 100%.
Created attachment 157623 [details] Just a sample file which shows the described behaviour. I don't believe, it's data-driven, though. The file contains "tag" names as logged from a wordpress site during page build, mildly edited and split into two "passes" next to each other in the two columns.. There is no private information included.
Thank you for reporting the bug. it seems you're using an old version of LibreOffice. Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ? I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.
Hi Xisco Fauli (couldn't determine which is your first name), I installed one of the latest releases of LibreOffice on my previous Debian "Buster" system and hope, I didn't ruin too much of my system along the way. Current LibreOffice version is now: Version: 6.4.1.1 Build-ID: 1:6.4.1~rc1-2 CPU-Threads: 8; BS: Linux 4.19; UI-Render: Standard; VCL: gtk3; Gebietsschema: de-CH (de_CH.UTF-8); UI-Sprache: de-DE Calc: threaded Using the same data file as originally attached, the error is still present. Actually I would even say, that the error has become slightly more serious along the way: now the high CPU load, which still occurs about 30 minutes after minification of the Calc window, does _NOT_ go away after the first click on "Save". Now it akes about 4 or 5 clicks on "Save" before the high CPU load goes away, according to the taskmanager, sorted by CPU-load.
Could it be related to Tools - Options - Load/Save - General: Save autorecovery info every x minutes? Try changing it to 1 and monitor the cpu.
(In reply to Buovjaga from comment #4) > Could it be related to Tools - Options - Load/Save - General: Save > autorecovery info every x minutes? Try changing it to 1 and monitor the cpu. Setting to NEEDINFO. @Chris, Please, try what Buovjaga suggested and give us feedback. BTW, my name is Xisco, my surname is Fauli :)
I updated my system and am now reporting the behavior of LibreOffice 6.4.4.1 : The setting as proposed in Comment4 was initially set to "10". I set it to "1" and monitored CPU-load for 30+ minutes, without the bug re-occurring. I then reverted the setting as proposed in Comment4 to "10", and monitored for another 30+ minutes. The bug then re-appeared after approx. 30 minutes, may have been slightly less. The CPU-load returned to normal idle value of 2% after "Saving" the calc file.
