I’ve seen one other English thread relating to this, of sometimes when I open an Office document, Calibri font doesn’t render.
I’ve actively seen it in Calc and Writer.
It’s USUALLY fixed by closing all windows and reopening the document. It’s sometimes fixed by me changing the font then changing it back - though sometimes it will remain when changing back to it. Rarely I need to restart the whole computer to fix it.
It was common enough in one calc document that I just changed the font to Bahnschrift because I needed the document to work every time.
I’m running
Version: 25.8.2.2 (X86_64)
Build ID: d401f2107ccab8f924a8e2df40f573aab7605b6f
CPU threads: 16; OS: Windows 11 X86_64 (build 22631); UI render: default; VCL: win
Locale: en-NZ (en_NZ); UI: en-GB
Calc: CL threaded
on a windows 11 computer with the TTF of calibri light installed as a base file
It’s set to 12pt Calibri as a default, which I know I can change.
I’m not sure if I should try and create a bug report since it happens seemingly at random, then will take different fixes depending on the day.
