Comment 3 Shinji Enoki 2022-08-23 13:00:54 UTC
I reproduced it by changing the zoom level or increasing the font size of the text.

For example:
Font "Noto Sans CJK JP", Font size "96pt", Alphabet may not be displayed

I see the problem in

CPU threads: 16; OS: Linux 5.19; UI render: default; VCL: gtk3

But it is solved in
