Description: Since updating to 25.2 (I've tested both 25.2.0 and 25.2.1), the options dialogs are essentially unusable, suffering from extreme lag. This happens on open, where a blank window can stay on screen for minutes, but also when navigating or trying to change values in panels. LibreOffice shows ~100% CPU alongside WindowServer 100%, even with no widgets or buttons shown. Reverting to 24.8 and options works again. THere are no clear errors, and using Writer itself seems fine, just options causes the lag. I deleted all my user settings and fully uninstalled LO and reinstalled, I still see this problem. I attach a spindump from Apple activity monitor when options dialog is frozen. 25.2 is wholly unusable on my system, luckily 24.8 works fine! Steps to Reproduce: 1. Open options dialog. 2. 3. Actual Results: Severe hang Expected Results: Functional options dialog Reproducible: Always User Profile Reset: Yes Additional Info: Version: 25.2.1.2 (AARCH64) / LibreOffice Community Build ID: d3abf4aee5fd705e4a92bba33a32f40bc4e56f49 CPU threads: 8; OS: macOS 15.4; UI render: Skia/Metal; VCL: osx Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded

I cannot reproduce this bug so I looked at your spin dump and noticed the following: 1. You are running macOS 15.4 which is a beta version 2. LibreOffice is waiting for some macOS system timer to finish 3. The macOS system timer appears to be trying to connect to the window server and keeps executing some system function called "kernel.release.t8112" Maybe you have found a macOS bug? Here's what I am running for comparison: Version: 25.2.1.2 (AARCH64) / LibreOffice Community Build ID: d3abf4aee5fd705e4a92bba33a32f40bc4e56f49 CPU threads: 8; OS: macOS 15.3.1; UI render: Skia/Metal; VCL: osx Locale: en-CA (en_CA.UTF-8); UI: en-US Calc: threaded

I just saw a similar spin dump in tdf#165277 and that was captured on macOS 15.3.1 so this isn't limited to macOS 15.4. Unfortunately, I cannot reproduce this on my machine but I'll take at look at the spin dump in tdf#165277 and see if I can find some potential pattern of what's going on.
When you say "options dialog" do you mean LibreOffice Settings (aka Preferences)?
(In reply to steve from comment #4) > When you say "options dialog" do you mean LibreOffice Settings (aka > Preferences)? Yes. I see -[MainMenuSelector showPreferences:] in the spin dump so in this bug, LibreOffice has created the dialog and is waiting for the next macOS event.
