Nate Graham, could you explain why it duplicates that bug? Telegram's developers claim that: KDE developers for some reason provide telegram icon in breeze with 48px size only that overrides telegram's 256px icon Well, all it takes is to delete the small icon from Breeze.
The Telegram developers don't have the whole story. They're right that our icon theme has a 48px icon in it, but it's a vector image, so it has no problem scaling up. So that's not the problem. The problem is that the window itself sets a small pixmap image and KWin honors that instead of ignoring it and using the icon from the theme instead. Which is what Bug 351055 is all about. *** This bug has been marked as a duplicate of bug 351055 ***
