Created attachment 185282 [details] Screenshot of a Plasma tray, showing Signals ugly/scaled symbol next to the stylish/fitting Telegram symbol For the instant messenger Telegram, KDE Plasma supplies a set of icons that fit the overall design of KDE Plasma. Other instant messengers, such as Signal, lack such a support. For them, the icons supplied by the programs are used. In the best case, they just don't match the other icons in the notification/status tray by color, in the worst case they get scaled and expose artifacts. This bug report is purely a look-and-feel issue, the actual functioning of tray icons is not concerned.
