Description Sunjae Park 2015-02-08 18:37:38 UTC 
When I try to switch to full screen mode in Konsole, and it was in maximized mode, the application jumps to non-maximized mode before transitioning to fullscreen mode.

When disabling fullscreen mode konsole switches to non-maximized mode, instead of the original maximized mode.

Not serious, but slightly annoying.

Reproducible: Always

Steps to Reproduce:
1. Maximize Konsole
2. Switch to fullscreen (i.e. hit F11)

Actual Results:  
Konsole temporarilly switches to non-maximized mode, then then grows to full screen..

Expected Results:  
Konsole should smoothly transition to fullscreen

If Konsole was NOT maximized, the fullscreen transition animation is smooth. 
When I disable fullscreen, konsole switches to non-maximized mode. It's as if konsole "forgets" that it was in maximized mode when I hit F11.

i.e. when enabling full screen:
Maximized Mode -> Non-maximized mode -> Fullscreen mode
but when disabling full screen:
Fullscreen mode -> Non-maximized mode

Which KWin version are you using? Please add the output of this Konsole command:

qdbus org.kde.kwin /KWin supportInformation

That's not related to KWin, konsole actually withdraws the maximized state - eg. utilizing the WM shortcut/alt+f3 entry to fullscreen it will rather behave as (can probably be) expected.

@ Christoph Feck
My KWin version seems to be 4.11.16. I posted the full output at

@Thomas Lübking 
You are correct: Using alt+F3 to go fullscreen does not trigger the bug.

Note: I am no maintainer but from the bugsquad.

I can reproduce this bug on my system.
I attached the software version used in my system and updated the konsole version in the description.

Unfortunately I do not know what triggers this bug.
It can be KWin oder konsole.

Additional notes:
It seems that spamming F11 (so fullscreen and back) is buggy.
Oftentimes I end up in a non maximixed window mode.

Please let me know if you need additional informations.
