System tray icon ugly in KDE Plasma

[xeruf]

The icon in the system tray in KDE Plasma has no borders separating the content from the remainder of the system tray, and as soon as there is more than 9 new messages, you can barely see the number.

This is a known upstream issue. Description and temporary solution described here vector-im/riot-web/issues/6767 comment .
Most electron apps seems to be effected by this on KDE. The fix has been made to chromium and soon should be in electron in its upcoming releases.
Two possible temporary solutions -

• Remove libappindicator3.
• set XDG_CURRENT_DESKTOP=Unity zulip

Ok. Just so you know, the way you linked to the comment did not work, but I found it anyway ;)

[abhigyank]

Sorry my bad. Thanks for letting know. Edited. Let us know if the fixes work for you.

Adding XDG_CURRENT_DESKTOP=Unity to the application starter indeed worked, while libappindicator made absolutely no difference.

Is the XDG_CURRENT_DESKTOP thing a workaround we can do for everyone, or will it cause problems for folks using other windowing systems?

[xeruf]

Shouldn't be a problem, since it is just an application parameter. You could even include it in the .desktop starter until the issue is resolved

I see this in my systray when Zulip has unread messages:
Is that the same bug, or shall I open a separate report?

Fedora 31, KDE Plasma 5.16.5, KDE Frameworks 5.61.0, Qt 5.12.5.

@devurandom the image is too small. Can you please post another screenshot/gif etc?

[fdcds]

@akashnimare The icon is very small on the screen too, so no idea how to enlargen it...

It shows a white rectangle with rounded corners, with the bottom right corner cut off. In the middle of the rectangle is a grey triangle with an white exclamation mark in the middle.

[akashnimare]

Hmm, looks like it's broken for some reasons.

I also had a look with my Gentoo Linux machine with KDE Plasma 5.17.3, KDE Frameworks 5.64.0, Qt 5.13.2 and the issue is the same.

[timabbott]

Is it possible we're just not registering the icon in the right way for KDE?

[akashnimare]

I don't have the KDE so it's hard to debug the root cause but as far as I know, this could be the platform-limitation from electron's side. They usually don't cover all the distros. For example, the badge api only works in Ubuntu 16+( with unity launcher).

The Zulip logo displays fine as long as Zulip has no internet connection. Once it has a connection, the logo changes to the one described in #620 (comment) and #620 (comment). I assume it is related to when it displays the unread message count.

A little bit confusing: I remember that at some point I actually saw the Zulip logo with a small "99+" in the systray at some point. But on none of my machines I get that right now.

Correction: Disabling "Show app unread badge" in the settings has no impact.

Addition: When I disable "Show app icon in system tray" and then re-enable it, I get a green circle with "99+" inside. This is independent of the "Show app unread badge" setting.
