Input Signal Target not Correct in Hyprland #1031

Closed The-Lost-Light closed 7 months ago

The-Lost-Light commented 7 months ago

Describe the bug 在fcitx5 5.1.9更新(降級至5.1.8後正常運作)之後, 在hyprland中快速切換焦點(A->B->A)會導致聚焦於A程式但輸入是對B程式的 After the fcitx5 5.1.9 update(downgrade to 5.1.8 still working fine), quickly switching focus (A->B->A) in hyprland will cause the focus to be on program A but the input is to program B.

To Reproduce

  1. open app1 and app2
  2. switching focus to app2 and return to app1 quickly
  3. any type is send to app2 even though the focus is on app1 (dragging the window can temporarily solve the problem)

Expected behavior app1 got the type when focus

    Following error may not be accurate because guessing Qt version from path depends on how your distribution packages Qt.

I just had this problem and was investigating it.

In my case, if I held down the mod key (Windows key) and changed windows, I could not type in the terminal (wezterm/alacritty/kitty etc). If I release the mod key once, I can type in the terminal.

So I need to this explain a little bit about how zwp_input_method_v2 works.

Fcitx has ZERO knowledge about App from zwp_input_method_v2, and it can't differentiate if there is 1 or 2 or 3 apps. The app you see in DebugInfo, is obtained from a side path that is also used to implement task manager. Fcitx can not control which application it is sending text to with zwp_input_method_v2

Basically, when fcitx send some text, it just send it to compositor blindly, and expect compositor to route it to the correct application. So this can only be a compositor bug. The focus management of text-input is done on the compositor side.

There may be some change triggered a bug in hyprland, but it's definitely not a fcitx bug.

I may just have found the change. b2924bd361680c493463d240a375b3f0948ae48d

By using git bisect, this is the result I get:

b2924bd361680c493463d240a375b3f0948ae48d is the first bad commit

    Destroy virtual keyboard when it is not activated.

    This seems to be a good idea to clear up all the xkb state we sent from
    vk. This seems also fix the hyprland issue that modifier is pressed when
    switch window.

@clsty yes, but I have no intention to change it back. Please report bug to hyprland. I ideally include the WAYLAND_DEBUG=1 log from two app.
