In '@ - QWERTY ⌘' keyboard layouts, COMMAND-H does not hide application when a conversation is selected

[Complexity]

Using a supported version?

• [X] I have searched searched open and closed issues for duplicates.
• [X] I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

Traditionally on Mac OS, using Command-H, the standard system-wide shortcut, will hide the current foreground app.

In Signal Desktop on Mac OS, when the app is in foreground and no conversation is selected, Command-H will perform as expected and hide the Signal app

However, upon selecting any individual chat by clicking in the middle pane, Command-H no longer responds and the app will not hide.

From this point forward, there is no way to deselect a chat, and so Command-H will never again function until the app is quit and restarted.

Steps to reproduce

1. Launch Signal Desktop on MacOS.
2. Before selecting any chat, use the Command-H shortcut and observe the app is hidden.
3. Switch back to the app to bring it to foreground and try a few times to confirm.
4. Select any chat.
5. Attempt to use the Command-H shortcut again. Observe the app does not hide.

Expected result

We would expect a system-wide shortcut to work and hide the app whether a chat were selected or not.

Actual result

The app ignores the Command-H shortcut and does not hide.

Hm... I don't think I can actually reproduce it, and I don't believe we have any shortcut that could interfere with it. Did it use to work for you before?

This has never worked for us. However, after some more investigation, this is something of an edge case.

Specific To Certain Language Layouts

We use Dvorak - QWERTY ⌘ keyboard layout on our machines. This is a standard Dvorak layout for typing but when the Command key is pressed the keys revert to the physical keyboard layout.

1. If Signal is started in a standard keyboard layout (e.g. US), Command - H works correctly.
2. If Signal is started in Dvorak - QWERTY layout, Command - H produces the reported incorrect behaviour.
3. If Signal is started in standard layout and then switched to Dvorak - QWERTY, Command - H works as expected with chats selected.

Observed In Other Layouts

As the - QWERTY ⌘ layout is also available for certain other international keyboards (1) we investigated a different language. In this case, Bulgarian - QWERTY ⌘.

We can confirm that the behaviour is also present for this language layout.

This would suggest there is an issue with all - QWERTY ⌘ layouts.

Workaround

There is a workaround available in this issue, which would be to ensure that Signal is always started in a non-QWERTY ⌘ variant layout before switching back to the preferred working layout for the language. However this is not ideal.

1. At last count we saw 34 international language layouts with a -QWERTY ⌘ variant, including Arabic, Hindi, Russian and others.

We can update the initial report for more specificity if preferred.

Ah, got it. Thank you!
