Fcitx5 lagging #1077

mhiuuu · 2024-06-13T04:42:58Z

Summary

I have reported this problem before but it seems like the solution doesn't fully fix it. I will leave a link to the video (it is quite big > 30Mbs so I can't put it here). The problem is, every time I use fcitx, the little box displays which kind of input I'm using is flies to the corner of the window, and after that, I will only have one input available to type yet the other one will freeze my input. But when I open OBS to record that, it is just fixed somehow????
Link to the video

Steps to Reproduce

Right after turning on fcitx5

Expected Behavior

One of your inputs will be frozen when the little box to show which input you are using will fly to the corner of the window

mhiuuu · 2024-06-15T06:33:12Z

I think the problem is fcitx5 conflicts with cliphist from hyprland

mhiuuu · 2024-06-15T17:40:37Z

Nah that isn't the problem

wengxt · 2024-06-15T18:15:06Z

Can you update to stable 5.1.10 and test again? From your backtrace I think you might be running the your own fcitx5-git or sth.

mhiuuu · 2024-06-17T16:07:01Z

Ye I'm currently using version 5.1.10. But I reinstalled the system and removed cliphist then it works smoothly although sometimes it also breaks down.

wengxt · 2024-06-22T01:07:11Z

I'm not sure how cliphist may affect here, but fcitx does also monitor clipboard (Only one way monitoring) for its own clipboard history feature.

If somehow, due to cliphist there was a message loop, that might be the cause.
But based on the protocol, I currently do not have an idea on how that could happen. You may want to run WAYLAND_DEBUG=1 fcitx5 and see if there's any suspicious message loop. (Including other issues you saw, mainly focus on the data offer, text_input messages)

Fustigate8933 · 2024-10-08T02:54:46Z

I have a similar issue with the little fcitx5 box on the top left corner. When that happens I can't change input methods in discord when kitty is open. When I close kitty, everything goes back to normal. Should I open a new issue?

mhiuuu · 2024-10-08T03:09:22Z

The problem remain unchaged for me but I learnt to live with it. It happens to me when I am in Vivaldi as it is the place where I need to change my language input. Asked on many forums but ye so maybe we should keep this issue open

wengxt · 2024-10-08T03:45:22Z

@mhiuuu it's interesting when you mention vivaldi. What is your wayland compositor and what's its version? Are you running a native wayland vivaldi?

mhiuuu · 2024-10-08T06:09:57Z

I'm currently running Hyprland v0.43.0 and Vivaldi was installed from yay. I don't know if that can help you but ye this also happened when I was using microsoft-edge too

wengxt · 2024-10-08T17:10:47Z

@mhiuuu do you run those browser with xwayland or native wayland?

Can you run fcitx5-diagnose again when the browser is running?

mhiuuu · 2024-10-13T04:16:15Z

Hi @wengxt, sorry for the late reply, last week was pretty busy for me. I switched back from Vivaldi due to compatibility issues with my keyboard. However, before switching, I did notice that the problem disappeared for a while (can not be sure if it will be back or not). As far as I know, the browser is running with XWayland

disjfjdizmfnkf · 2024-11-02T11:56:06Z

Hi @wengxt , Could it be that fcitx5 is unable to properly detect the program I want to input into? I am using Hyprland, and the bug often occurs when I switch between JetBrains IDE and Chrome. At that time, only Chrome allows input Chinese; if I try to type in the IDE, the candidate box appears outside the window. If I close Chrome, it returns to normal. Similarly, when I have two instances of Chrome open, only one of them can input Chinese. Is the key issue related to my use of Hyprland?

wengxt · 2024-11-02T15:33:35Z

@disjfjdizmfnkf

on wayland, fcitx has no control on what client it talks to. fcitx only talks to compositor, and compositor forward it to right application. The focused client is managed by compositor, not fcitx.

mhiuuu · 2024-11-03T07:12:18Z

@disjfjdizmfnkf dont know if it would help but I use Microsoft edge and the problem is gone. Altho once I did see it again but never more. Im not telling you to switch or something but rather giving it a try. Here is the link to my question on r/hyprland here

disjfjdizmfnkf · 2024-11-03T07:54:41Z

@wengxt 谢谢！我从你的回答中了解了新的知识

disjfjdizmfnkf · 2024-11-03T09:01:37Z

Hi @mhiuuu ，thank you for your suggestion. I tried switching to a different browser (Firefox) as you suggested, and it really worked. I tried to trigger the same bug using Firefox , but nothing happened, although I don't know why.
