When live resizing a window on macOS, there is a brief flicker after each resize but only when using Skia/Metal. Steps to reproduce: 1. In LibreOffice's Options dialog in the LibreOffice > View panel, enable Skia/Metal by setting the following checkboxes, press the OK button, and restart if prompted: - Check "Use Skia for all rendering" - Uncheck "Force Skia software rendering" 2. Open a new Writer or Calc document and and live resize the window via a mouse dragging a window edge or corner. With Skia/Metal, the toolbar area will flicker with every mouse drag until you release the mouse. This bug does not occur with Skia/Raster or Skia disabled so my guess is that there are some missing flushes to screen when using Skia/Metal.

I have committed a fix and the fix should be in tomorrow's (10 December 2023) nightly master builds: https://dev-builds.libreoffice.org/daily/master/current.html Note for testers: the nightly master builds install in /Applications/LibreOfficeDev.app. These builds are not codesigned like regular LibreOffice releases so you will need to execute the following Terminal command after installation but before you launch /Applications/LibreOfficeDev: xattr -d com.apple.quarantine /Applications/LibreOfficeDev.app
