--- Comment #5 from Guo Yunhe <i...@guoyunhe.me> --- I am in a hospital and the wifi doesn't allow me to download large files... These special languages fallback to GNU Unifont because it is the only font that cover these characters. I found that if you change the editor's font to GNU Unifont, then no matter what file you open, the editor is super slow when scrolling and editing. Also I am using 150% scaling in X11. It may affect. -- You are receiving this mail because: You are watching all bug changes.
