Additional Information

This may caused by #21904 , as it downscales every image to 22x22.

I guess this change #21904 might have something to do with the issue.

PS Didn't notice the point initially:

The Electron version reported on this issue is no longer supported. See our supported versions documentation.

If you're still experiencing this issue on a supported version, please open a new issue with an updated repro - a Fiddle is very appreciated.

Electron has a large issues backlog. To help our team prioritize, we're closing older issues and asking for new issues with updated repro steps if it affects a supported version. This helps sort what issues are still relevant and helps us fix them more quickly.

Thanks for your patience and understanding!

Seeing the same issue with 11.4.x. I'm surprised no one else is reporting this. I figured it must be some mistake in our implementation at first, but by the third day of trying to resolve this, I have to conclude it's Electron.

@rocka did you ever resolve this? Things just don't look right in KDE.

Top: Our 22x22px image
Bottom: Our 22x22px image in the KDE tray

If anyone has any ideas, I'd be very appreciative. This is how it looks even with the latest version of KDE - 5.24.1

Looks like this isn't an issue with snap packages, so I'm guessing there's nothing that can be fixed on Electron's side.

[Nantris]

Looks possibly fixable via installing libappindicator-gtk3, so really nothing to be done on Electron's side I guess - but it's a shame because for users not running Arch, it's pretty tedious to get up and running.

This thread also mentions libappindicator-sharp as possibly helpful.

@slapbox FWIW, Element Desktop does not have this issue on my side (also under KDE, without libappindicator-gtk3).

[Nantris]

Hmmm that's very curious. Thanks for sharing @ArchangeGabriel!

[Nantris]

Fixed this by accident on KDE by installing libappindicator3-1.
