Description: Animating text box requires quite some CPU time on MacOS Steps to Reproduce: 1. Open the attached file 2. Open Apple Instrument and make a time profile or look at the Activity Monitor Actual Results: For me 18%; but not the fastest CPU Expected Results: 2-5% based on Linux/Windows Reproducible: Always User Profile Reset: No Additional Info: Version: 7.0.0.1 Build ID: 04ba7e3f1e51af6c5d653e543a620e36719083fd CPU threads: 4; OS: Mac OS X 10.12.6; UI render: default; VCL: osx Locale: nl-NL (nl_NL.UTF-8); UI: en-US Calc: threaded

Dear Telesto, Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ? You can install it alongside the standard version. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build
@Telesto : where exactly should I be looking in the time profile ? On Mac Silicon M1, using Version: 7.0.3.1 Build ID: d7547858d014d4cf69878db179d326fc3483e082 CPU threads: 8; OS: Mac OS X 10.16; UI render: default; VCL: osx Locale: fr-FR (fr_FR.UTF-8); Langue IHM : fr-FR Calc: threaded I see a faire amount of time is spent in what I assume is the render operation : 223 ms ripc_RenderImage CoreGraphics and more specifically in: vPremultipliedAlphaBlendWithPermute_RGBA8888_CV_sse4 but is this where I should actually be looking ? I guess the SSE instruction set execution is the slow point here ? However, in the grand scheme of things, at least from my perspective when viewing the text animation, the animation occurs at a perfectly acceptable speed. Sorry I can't help more, as I don't really know which bottleneck I'm supposed to be searching for. There are other bottlenecks which take up more time overall, for example in the NSViewBackingLayer loop.
Not sure if this even around any longer.. HDPI screen should be the most affected. But well there where some changes in rendering

Hmm, like I said, the animation for me, whether output onto my MBPro Retina M1, or via lightning to my 27" HDPI Apple Monitor, is perfectly acceptable. Shall we set this to WFM ?
