You have to click twice when a window is out of focus to have actions performed

I confirm (by marking "x" in the [ ] below):

• This is not a troubleshooting question. Troubleshooting questions go here: http://www.mattermost.org/troubleshoot/.
• This doesn't reproduce on web browsers (such as in Chrome). If it does, issue reports go to the Mattermost Server repository.
• I have read contributing guidelines.

Summary

When the Mattermost window is not in focus, you have to click twice on any UI element to have that action performed.

For instance, change the channel or selecting a direct message.

Steps to reproduce

• Operating system is Mac OS X
• Server version is Version: 3.7.0 (3.7.3)
• Desktop Version is 3.6.0

This is a simple one to reproduce:

• Open another window on your desktop, such as a web browser and make sure it has focus
• Click on a different channel, such as Town Square, or a direct message

Expected behavior

The click will perform the action to change the channel or direct message

Observed behavior

The desktop app is in focus, but the click is not registered, and you have to click again

Possible fixes

Not sure, might be an Electron related issue

Thanks @cetra3 for the report!

We fixed a similar issue with #262 but that was a while ago. I also tried reproducing on Windows 10, and it seemed to be working for me.

Would you like to download our newest release (desktop app v3.7) from our downloads page (https://about.mattermost.com/downloads) to confirm the latest release doesn't fix the issue?

[cetra3]

@jasonblais,

I've just given the new version a download. Same issue in 3.7.0. It might be a Mac OS X specific thing. The other thing to note is that the mouse cursor is still the default pointer rather than the click before focus is given.

[jasonblais]

True, it could be Mac specific.

Just one more test case: when you click on the window, do keyboard shortcuts work for you (for instance, after clicking inside the app window, does CMD+K bring up channel switcher, or do you have to click inside the app twice before the shortcut works)?

[cetra3]

Yep, the channel switcher works fine after clicking into the window

[jasonblais]

Thanks! That's helpful to know. We should have enough information to investigate the cause and whether it's something we can fix or if it's an Electron-related bug.

[yuya-oc]

Sorry for late. I think it's expected behavior in Electron. Basically the window should behave as well as Chrome.
Actually on macOS, Chrome also requires a click to take focus, then you can perform actions in the window.

[jasonblais]

@yuya-oc forgot to come back to this. Thanks for the response.

@cetra3 sounds like this is consistent behaviour with browsers on macOS. Would you like to help try if you see the same behaviour on the Chrome browser?

[cetra3]

@jasonblais It's the same behaviour. Can this be switched off via some electron flag or something?

[jasonblais]

Thanks @cetra3, doesn't look like it: electron/electron#5900

@yuya-oc There seems to be a potential workaround for it, but it wasn't working for everyone: electron/electron#5900 (comment)

If the above workaround doesn't work, then there isn't much we can do.

[yuya-oc]

@jasonblais The workaround is already applied to our app.

The issue is a little different from this. The point is that Electron's BrowserWindow requires a click before handling mouse events on macOS. And I think it looks consistent compared to Chrome.

[jasonblais]

Thanks @yuya-oc I see.

@cetra3 Unfortunately I don't think there's much we can do at this point. I'll leave the issue open for now with the Electron label.

[jasonblais]

@cetra3 The Electron issue was closed without a fix.

We don't have control to change this behaviour at the moment, given this is how it works on Chrome as well. So I'll regretfully have to close this issue as a Won't Fix.
