When I type using the Text tool in preview window, the word won’t appear until I press space. I find this annoying since I won’t get to see the kerning change, for example, first I type Ta, then I change it into Tâ (in which â is not kerned), I won’t get to see the change and it’s harder to notice that I haven’t added â to kerning group a.
I have no issue with the English keyboard. Maybe something is wrong with the Vietnamese keyboard, but I’ve been using it in 2.4 and everything is fine though.
