When I undo a paragraph tab stop action, like adding a tab or moving its position - it takes about a second for the rulers to reflect this action. This is on a machine which is not under heavy load, with plenty of free RAM, with 4 cores etc and when otherwise the UI is pretty responsive. This is in stark contrast to the original action, which, if performed using the ruler, seems instantaneous.
Seeing the same thing with the action of setting a first-line indent. Even with an empty Writer document.
Please add more information on how to reproduce this error. I dont seem to have this issue running the latest and dev versions on Mac. == testing == Version: 25.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 3287deb82ef0ee2048f733ae981961f527888727 CPU threads: 8; OS: macOS 13.7; UI render: Skia/Metal; VCL: osx Locale: pt-BR (pt_BR.UTF-8); UI: en-US Calc: threaded Version: 24.8.2.1 (X86_64) / LibreOffice Community Build ID: 0f794b6e29741098670a3b95d60478a65d05ef13 CPU threads: 8; OS: macOS 13.7; UI render: Skia/Metal; VCL: osx Locale: pt-BR (pt_BR.UTF-8); UI: en-US Calc: threaded
