Electron Version

31.0.1

What operating system are you using?

Ubuntu

Operating System Version

Kubuntu 24.04

What arch are you using?

x64

Last Known Working Electron version

30.1.x

Expected Behavior

globalShortcut works from all applications

Actual Behavior

globalShortcut is ignored in some application (eg Sublime Text) despite not having any interfering local shortcut in that application.

Testcase Gist URL

No response

Additional Information

It works fine if the focused application is Chrome, Android Studio, or the Android Emulator

It fails if I focus Sublime Text, Firefox, Dolphin, or no applications.

Specifically testing using Ctrl+Shift+Z and Ctrl+Shift+X

This seems to have been reported years ago and simply rejected as a wontfix? #15863 That would make all our years of development a waste if that's really not going to be fixed.

Hello @Nantris. Thanks for reporting this and helping to make Electron better!

Would it be possible for you to make a standalone testcase with only the code necessary to reproduce the issue? For example, Electron Fiddle is a great tool for making small test cases and makes it easy to publish your test case to a gist that Electron maintainers can use.

Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.

Now adding the blocked/need-repro Needs a test case to reproduce the bug label for this reason. After you make a test case, please link to it in a followup comment. This issue will be closed in 10 days if the above is not addressed.

@VerteDinde I cannot test this Electron Fiddle since Electron Fiddle is broken in Kubuntu 24.04, but this problem is exceptionally straightforward to demonstrate and this Fiddle should work: https://gist.github.com/07f00c727fca205776f8abae9aec3c40
