If I delete a long word with the backspace key, the cpu rises up du 13% and the green "progress bar" down in the status line is visible for a secound or so. The process is slow (much slower than tiping the same amount of letters). The document is around 60 pages but with a lot of formulas (~200). Is this a known "problem"? Tested with 5.4.2.2 and 5.3.6.1 Thank you very much for your work on this great piece of software!
Thank you for reporting the bug. You're probably on to something (I did a quick test with quite different document). Please attach a sample document. So I can check if it's the same bug. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' once the requested document is provided. (Please note that the attachment will be public, remove any sensitive information before attaching it. See https://wiki.documentfoundation.org/QA/FAQ#How_can_I_eliminate_confidential_data_from_a_sample_document.3F for help on how to do so.)
Created attachment 136936 [details] Testdocument Hi, thank you for your fast answer! I have an idea of the "bug": It is due to the "change log". If the changes are visible, everything is very fast and responsive - works like a charm. But if the changes are hidden (while recording the changes), the deletion of a letter is slow and costs "a lot" of CPU power... Sorry, I didn't know, that I was recording the changes and it tooks me 2 hours to reproduce the problem with a fresh document... But here it is... Thank you all for your phenomenal work on LibreOffice!
I used the attached document. That’s right when using back space to delete or undo button the CPU utilization jump from 2 % to 30 % and more. Even I tried to reproduce the issue with two other different files, I got the same situation. Test environment : • Operating system : Windows 8.1 Pro 64-bits. • LibreOffice : Version: 5.4.2.2 Build ID: 22b09f6418e8c2d508a9eaf86b2399209b0990f4 CPU threads: 4; OS: Windows 6.2; UI render: default; Locale: en-US (en_US); Calc: group

Opening + testing Comment #8's document, I pretty much got the same exact symptoms as Comment #7's video using: Version: 24.2.0.3 (X86_64) / LibreOffice Community Build ID: da48488a73ddd66ea24cf16bbc4f7b9c08e9bea1 CPU threads: 8; OS: Windows 10.0 Build 22631; UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL threaded - - - 0. Open attachment 144322 [details]. 1. Click at the end of a line. 2. Hold down BACKSPACE. And you could see LO chugging/stuttering. I also tested: - Holding down the DELETE key. - Same exact symptoms. - - - Comparing between a few different programs... Deleting one whole line of text with backspace: ~11 seconds = LibreOffice 24.2 ~3 seconds = Word 365 (Version 2401, Build 17231.20194) ~3 seconds = Notepad++ v.8.6.2 In LibreOffice, it was: - stuttering/jerking around. - Some characters deleted fast, others stalled/slow. In Word/Notepad++, there was: - absolutely 0 slowdown. It seemed to delete that amount of text at the same exact speed whether it was in a really short paragraph or the super long/"slow" one.
