Attachments: A screenshot after launching second KCalc instance

Description Māris Nartišs 2013-08-16 13:16:05 UTC 
When launching any KDE application (tested with Okular, KCalc, Dolphin, Kate) and desktop has at least one window present (in task bar), application is displayed to be in "starting" state forever until it's window is activated i.e. by clicking on "launching" indicator in task bar.

Reproducible: Always

Steps to Reproduce:
1. Start any application.
2. Start a second application.
3. Observe task bar.
Actual Results:  
Application is starting infinite time.

Expected Results:  
When application has started (or failed to start), task bar should indicate it as it has been before 4.11.00

A screenshot after launching second KCalc instance

A screenshot showing taskbar state after launching a second KCalc instance. Presented state will remain unchanged until a redraw of task bar is triggered i.e. by clicking on KCalc <2> window it self or it's "launching" indicator in task bar.

Plasma 5.7 ships a fully-rewritten Task Manager backend which should resolve these issues. Please re-test with the Plasma 5.7 final release and feel free to reopen if problems do persist after all.
