Hi! I'm not sure if it's intended behavior, but it seems weird to me so I'll report as a bug: On the task bar (k button to left, system tray to right) where programs sit, when for example an app has a download happening, a file transfer progresses in Dolphin, things like that where the bar for the app lights up as a horizontal progress indicator for the event... Why does it light up as a progress bar all windows for that application, instead of just the one registering the progress?
Component should be 'Task Manager'.
There's currently no way for us to tell what window a progress belongs to, we only know the application. This is definitely on the agenda but is not something that can be fixed short term.
