Wayland (Sway) Support

[glyh]

Describe the bug
If the problem is about you can not use fcitx in certain application, or the input window is placed in wrong place, be sure to include which application is being typed, and the output of fcitx5-diagnose command.

To Reproduce
Steps to reproduce the behavior:

1. Open chromium with "--enable-features=UseOzonePlatform --ozone-platform=wayland", try to type, but I can just input english.
2. Open alacritty, try to type. Successfully type something but I can't see the pop-up window, so I don't know what I'm typing. Also, because of fcitx5 is running in the background, it make alacritty lags all the time.

Expected behavior
A clear and concise description of what you expected to happen.
My input is hooked by fcitx5, and I can see the pop-up window by IME.

Desktop (please complete the following information):

• Window Manager: Sway
• Display server type: Wayland
• The output of fcitx5-diagnose if possible.

Additional context
Add any other context about the problem here.

This seems long been a problem that mainstreams IMEs don't have good support for Wayland.

The Same. I also have the same problem about typing in alacritty as you and i am in a mess.

[haolian9]

According to the todo-list of fcitx, wayland support is in progress status.

However, you can use xwayland to make fcitx work in wayland environment. (based on my fcitx4 experience, may not apply to fcitx5)

I think that the problem is hidding in Ozone and Google's work. Here is some bug report I found in their issues: Issue 1183262: Add support for gtk im module on ozone wayland platform

As it said, the input protocols under wayland whitch chromium supports are out of date. Maybe the only thing we can do is wait google update them.

By the way, if u really need to type chinese in chrome, u can install "google input tools" from google web store. I'm using it now, 呃，感觉还行，比没有强。

我已经在用了 XD

Why this is closed? is wayland support available?

[wengxt]

because it’s not a fcitx issue. chromium need to fix by chrome and sway need to support input pop up surface. Lyhokia ***@***.***>于2021年10月3日 周日17:05写道：

I still can't make it work, did anyone have a solution?
