Not work normal on some applications

[zenfas]

I try keyman with keyboard Vietnamese_telex or Vietnamese_vni and see some points. I don't know error belong to fcitx or keyman

1. On Libreoffice, Konsole, Firefox not work normally. Example:
   Type: gox tieesng Vieejt
   Expect: gõ tiếng Việt
   Result: goõ tieêiếng Vieêiệt
2. Sometime fcitx auto switch to another keyboard
3. Icon for each Keyman IMs are the same

Good point: with Kate app, work normally. Specially, I can comeback to edit word after press spacebar (I don't know why keyman can do this)

[wengxt]

I guess the reason is pretty simple, those app doesn't support surrounding properly.

Actually the way that how keyman work would be pretty poor, especially on wayland due to pretty broken surrounding and forwarding key support.

If not using surrounding, on x11 continously do things like continously forward 4 backspace also won't get stable result.

[wengxt]

Given the poor state of surrounding text two potential workaround can be done.

Either, 1. Change the implementation entirely to preedit based ones
2. if we still want to simulate forward key backspace (Not even work for all cases, especially Gtk4), add delay between every event sending from input method.

Qt doesn't have ability to declare whether a client can support surrounding (e.g konsole case), only option for selective filter the surrounding support is also impossible without having specific app name (not possible under wayland too).
