--- Comment #22 from Patrick Luby <[email protected]> --- (In reply to Noel Grandin from comment #20) > Could be something we could do on our side (maybe a harfbuzz setting), or > maybe we are using the API wrong OK. I've got a potential fix at https://gerrit.libreoffice.org/c/core/+/163674. One (hopefully minor) inefficiency in the above patch is that if we copy the 'sbix' and 'glyf' font tables' memory every time LogicalFontInstance::GetGlyphBoundRect() is called. When running the Instruments application on macOS attached to my local build with the patch, I can see a very brief spike in memory usage when opening a new Writer document. Presumably that is the loading and releasing of the color emoji fonts' 'sbix' and 'glyf' tables. -- You are receiving this mail because: You are the assignee for the bug.
