Description Christian (Fuchs) 2010-06-07 22:37:01 UTC
Version:           SVN (using Devel) 
OS:                Linux

In KDE 4.4.81 the pack window left/right/up/down functionality is no longer working. It produces strange results, as an example 

xwininfo: Window id: 0x360004e "fuchs@thinkfox:~"

  Absolute upper-left X:  4
  Absolute upper-left Y:  305
  Relative upper-left X:  0
  Relative upper-left Y:  0

  Height: 65509
  Depth: 32
  Visual: 0x23
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x3600001 (not installed)

  Corners:  +4+305  --64092+305  --64092--64914  +4--64914
  -geometry 65528x65509+0-55


This is reproducible with all applications. I use the hotkeys to activate this. Desktop effects are enabled, but this doesn't seem to make a difference

Reproducible: Always

Steps to Reproduce:
Enable pack window to the left/right/up/down for any window with kwin 4.4.81

Actual Results:  
a huge window is produced on the outside of the desktop, eating almost all memory when desktop effects are enabled

Expected Results:  
the window is packed to the right/left/top/bottom 

gentoo, x86_64, KDE 4.4.81 from the KDE overlay
Comment 1 Christian (Fuchs) 2010-06-07 22:59:17 UTC
Sorry, I forgot to mention: 

I have a single screen setup, one 1440x900 Notebook TFT. 
The driver in use is the nvidia binary driver. 

Xorg is 1.8.1 and Qt is 4.7 (from Nokia trunk) 
Due to limited time (final exams) I can't do deep tests with different software versions, sorry. Hope you are able to reproduce it anyway. 

Kind regards, 

Christian

I didn't know that this feature existed, but on special request I can confirm that it doesn't work.

KWin 4.4.95 (RC3)
Window packing also didn't work. As for me pack to left/up/down simply makes nothing and to right (when it used first, not after left/up/down direction) - hides window and application 'eats' about 2GB of RAM (no more, though it can - I use x64 system with 4GB of RAM and 5GB swap).

SVN commit 1169432 by graesslin:

Fix window movment regression (e.g. pack) in 4.5.

The regression was caused in tiling which set the geometry to a different one again.
Nikhil please verify that tiling is still working correctly. Looking at the code this
commit should be side-effect free. When coming from Client::move() moveResizeGeom and
initialMoveResizeGeom may not be set. So I think the code in notifyTilingWindowMove()
cannot work at all ;-)

Fix confirmed. 

The change works in 4.5.0, I will patch 4.5.1 manually and I am glad that this will be in 4.5.2. 

Thanks for the good work as usual, Martin. 

Kind regards
