Description Dave Flogeras 2016-06-29 23:08:07 UTC 
I am running a multi monitor setup.  I have a task manager on each screen's panel, and set to only show windows from the current screen, desktop, and activity.

If I open a konsole on the first screen (primary monitor if it matters), for a second the second screen's task manager displays an entry for the window, and just as quickly as the animation is finished, it disappears, reappearing on the correct monitor's task manager.

Reproducible: Always

I think this is unfixable on X11 because startup notifications have no associated screen. We don't know what screen to put it on until the actual window appears. Right now, the notification should be shown in all Task Managers simultaneously, though. You only see "the animation" in one of them?

Even on Wayland that doesn't sound fixable.

Hmm, there seems to be more to it.  It seems what I am noticing only happens when I use a shortcut.  I use a _LOT_ of konsoles so I have it bound to a keyboard shortcut so I can create them quickly.  This seems to only happen when starting from shortcut.  So here is what happens:

1. Focus is on the first screen
2. Press shortcut
3. On _both_ screen's task managers, an entry quickly appears which just says /usr/bin/konsole, simultaneously an entry appears with the windows actual title (in my case "dave : bash@hostname...").
4. Very quickly, on both screen's task managers, the generic /usr/bin/konsole entries go away.

If I just start console by clicking in the launcher, or via krunner, the transient windows do not appear

Closing, it went away with plasma 5.7.0.
