Caprine: App icon problem in Linux

[dusansimic]

I have a problem with icon i Ubuntu 17.10. The icon is default application icon (not electron icon) but when Caprine is opened it has separate indicator from the pinned one but this indicator HAS an icon tho it is larger size.

The fourth icon from top is pinned Caprine and the last icon is opened Caprine window indicator. The last icon clearly has higher resolution and it looks ugly.
I haven't tried on any other distro tho.

By the way I've been building Caprine myself lately and this has appeared somewhere around commit that updated build directory structure (https://github.com/sindresorhus/caprine/commit/065aa47ed191f2d251a134b8947b7d7131d41d8f).

• Electron version: 1.7.10
• OS: Ubuntu 17.10

Same on Mint 18.3 and Docky, it uses the default icon. No unread badges visible either (not sure if this is supported on Docky, but if not it would be a great addition). Screenshot attached.

Any update on this?

The unofficial Microsoft Teams electron wrapper has no problem with this and the code should be quite similar i suppose: https://github.com/ivelkov/teams-for-linux

[dusansimic]

Well the solution to the problem is simple. Add icons folder in build that contains icons of different sizes like in ivelkov/teams-for-linux. This would be just a temporary solution until this issue is fixed in electron-builder! Any thoughts about adding this @sindresorhus? I can do a PR for this.

Note: This is a fix for Linux only since this issue appears only on Linux.

[sindresorhus]

I've done the recommended workaround in 2.13.0.

[dusansimic]

Thanks!

[sindresorhus]

Keeping this open so I remember to revert it when it’s fixed in electron-builder.

[michaelarnauts]

The workaround made sure that the icon was there, but it's not linked to the .desktop file, so if you add it as a favorite, it's a different icon as the running instance.

I think it is missing a StartupWMClass property.

[michaelarnauts]

Allright, adding a StartupWMClass=caprine fixes that. Who creates that desktop file? Is it also electron?

[sindresorhus]

electron-builder

[michaelarnauts]

It seems this is controlled trough the linux.desktop parameter in the package.json.
See https://github.com/ivelkov/teams-for-linux/blob/b107aa8e9078d3f9c64e8b4b985ceb83816024a6/package.json#L38

I'm not sure how to test this, but I guess this could work: https://github.com/michaelarnauts/caprine/commit/b6d28a7cbf8f2d6a6f5ad78d2eb854d577b729a1

[sindresorhus]

@michaelarnauts This should be fixed in electron-builder. Open an issue over there.

[dusansimic]

This issue is resloved. Closing the issue.
