I had a quick grep through the > codebase and I think SkiaZone::hardDisable() is being called for some reason? I think you are seeing a known Skia/Metal bug. In most cases, using Skia/Metal is a lot faster than using Skia/Raster. But, every once in while, Skia/Metal gets stuck in a very lengthy loop and LibreOffice appears to be hanging. To handle this unpredictable Skia/Metal behavior, LibreOffice has a background thread (i.e. the "Watchdog" thread) that detects if Skia/Metal has been stuck for several seconds. If yes, LibreOffice invokes SkiaZone::hardDisable() which switches to Skia/Raster to break out of whatever loop Skia/Metal is stuck in. If you are seeing SkiaZone::hardDisable() frequently, you may want to consider downloading LibreOffice 24.2 Beta1 from the following URL. That version already has the fix for tdf#155266 that LibreOffice 7.6.4 is missing so you should be able to use Skia/Raster with LibreOffice 24.2 Beta1. LibreOffice 7.6.5 will include the missing fix, but IIRC that won't be released until February 2024: https://www.libreoffice.org/download/download-libreoffice/?type=mac-x86_64&version=24.2.0&lang=en-US Note: LibreOffice 24.2 Beta1 will not overwrite your LibreOffice 7.6.4 installation. Instead, it will be installed in /Appplications/LibreOfficeDev.app so that you can run both 24.2 Beta1 and 7.6.4 at the same time. -- You are receiving this mail because: You are the assignee for the bug.
