Description Haakon Nilsen 2013-05-26 15:14:01 UTC 
When I have an ongoing chat in a window in the background, and my chat partner sends a message there, the window "demands attention" - its entry in the taskbar blinks. I always use the standard Ctrl+Alt+A keyboard shortcut of KWin to bring attention-demanding chat windows to front. But in Text Ui, there is a delay between the windows starting to demand attention and the keyboard shortcut working – it seems like five seconds, but it's hard to tell, so I will just repeatedly press Ctrl+Alt+A until the window appears. This is frustrating, and other applications don't behave this way. If it's not a bug, it's certainly a very strange and counterintuitive feature.

Reproducible: Always

Steps to Reproduce:
1. Get someone to send you an IM message
2. Immediately when the window's taskbar entry starts blinking, press Ctrl+Alt+A
3. Nothing happens. After five seconds, goto step 2, and the window will appear as expected.



I'm using the Kubuntu packages, and they don't seem to have any newer than 0.6.1, so I have not tested on 0.6.2.

Works fine here. Basically instant.

Can anyone else confirm that it does or does not work for them?

Got a friend to test, and he could reproduce it on 0.6.2.

Confirmed, though turns out... a bug in plasma.

What is happening is that the notification demands attention at the same time as the window. KWin selects the notification widget in plasma when you press the shortcut which doesn't do anything.

(I tend to run colibri, hence didn't see this)

Thanks to Martin Gräßlin for suggesting that as a possibility.
Fix will need to be in Plasma, as that's where the bug is. We could bodge it by delaying the notification by a few ms, but that doesn't really fix the problem.

I'll try and fix this plasma side.
