[zolitacs]

SUMMARY | 问题概要

Viber AppImage , or ANY appimage ignores the configured Hungarian keyboard layout on Deepin Linux (X11) and uses the US keyboard layout instead.

SOFTWARE/OS VERSIONS | 软件/系统版本信息

Distribution: Deepin v25.2.1
Kernel:6.6.143

PRE-REQUIREMENT | 预置条件

Deepin Linux
X11 session
Viber AppImage
Hungarian keyboard layout configured via Fcitx5
Other applications correctly use the Hungarian keyboard layout

STEPS TO REPRODUCE | 复现步骤

Start Viber AppImage.
Try typing Hungarian accented characters such as áéíóöőúüű.
Run setxkbmap -query and observe that the layout is us.
Run setxkbmap hu.
Try typing the Hungarian accented characters again in Viber.

OBSERVED RESULT | 观察到的结果

Viber uses the US keyboard layout and Hungarian accented characters cannot be entered correctly.

After running setxkbmap hu, the Hungarian keyboard layout works correctly in Viber.

EXPECTED RESULT | 期望的结果

Viber should respect the active system/Fcitx5 keyboard layout without requiring setxkbmap hu to be executed manually.

ADDITIONAL INFORMATION | 额外补充

The system uses X11, not Wayland.

Before running setxkbmap hu:

$ setxkbmap -query
layout: us

After running:

setxkbmap hu

Hungarian keyboard input works correctly in Viber.
