Description tony 2010-07-06 08:52:17 UTC

Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

With twinview (didn't tested xinerama), if one screen has a panel on bottom and the other has the panel on top, applications that have been closed maximized will not be maximized anymore on opening.

Reproducible: Always

Steps to Reproduce:
* Have an nvidia card and setup a dual screen twinview system (didn't tested with xinerama)
* remove all panels from screen 1 and screen2
* right click on plasma-desktop on screen 1 and select "add new" panel
* Configure it and move it to the top screen edge
* right click on plasma-desktop on screen 2 and select "add new" panel
* Configure it and move it to the down screen edge
* close all dolphin instances
* open dolphin and move it to screen 1
* maximize dolphin
* close dolphin
* open dolphin



Actual Results:  
Dolphin is no more maximized (blank space on the bottom)


Expected Results:  
To have dolphin still maximized.

The bug can be reproduced with other applications too, and it happens on screen 2 too.
I tested openbox windowmanager too and it works as expected, so i think it is a kwin issue.

Under kde 4.6.2 this bug changed into something funny.
If i logout and login, the panel that should stay on the top of the screen on screen 1 appears in the middle of the screen on screen 2.
You can still move it where you want, but logging out and in again makes it appears in the middle of screen 2 again.

Is this bug still valid in a later version of KDE (4.6 or 4.7)?

Comment 3 tony 2011-07-12 13:43:50 UTC

Under 4.6.5 it is not fixed.

Comment 4 Thomas Lübking 2011-07-12 14:06:17 UTC

I'm under the impression that the major source of these issues are the shadows of the panel & the strut setting (bug on plasma's side, timing issue?)

There's a good chance that this is fixed in 4.7 because
a) the shadows work differently
b) the maximization state is unliked from the actual geometry.

but I don't see what should have fixed it before.

Or maybe kwin think that the panel which is at the bottom of the screen 2 expands till the screen 1.
This happens only when the window appears.
