--- Comment #2 from John Louis <[email protected]> --- I completed the requested testing. 1. Skia software rendering I enabled "Force Skia software rendering" (LibreOffice → Settings → LibreOffice → View), restarted LibreOffice, and verified in Help → About that the UI renderer changed to: UI render: Skia/Raster VCL: osx With Skia/Raster, the resize jitter disappears completely. Window resizing is smooth and I can no longer reproduce the issue. After unchecking "Force Skia software rendering" and restarting LibreOffice, the renderer returned to Skia/Metal and the resize jitter consistently reappeared. The testing was performed on the MacBook Pro's built-in display only (no external monitor or dock connected). 2. GPU information Graphics/Displays: Apple M1 Pro: Chipset Model: Apple M1 Pro Type: GPU Bus: Built-In Total Number of Cores: 16 Vendor: Apple (0x106b) Metal Support: Metal 4 Current environment: LibreOffice 26.2.4.2 (AARCH64) macOS 26.5.2 Based on these tests, the issue is reproducible with Skia/Metal on my system, while enabling Skia software rendering (Skia/Raster) serves as a workaround. -- You are receiving this mail because: You are the assignee for the bug.
