I'd like to report few bugs I believe are due to the compiz component on
a fresh ubuntu amd64

If this mail should not be sent here, please direct me to the proper


summary: recent upgrade has it wrong when resizing windows, running
`Window management scale', Ring switcher, about what `fullscreen' is
when using multi-display desktop


$ aptitude show compiz
Package: compiz
State: installed
Automatically installed: no
Version: 1:0.8.4-0ubuntu2.1
Priority: optional
Section: x11
Maintainer: Ubuntu Core Developers <ubuntu-devel-discuss at>
Uncompressed Size: 77.8k
Depends: compiz-core (>= 1:0.8.3), compiz-plugins, compiz-gnome |
         compiz-fusion-plugins-main (>= 0.8.3),

         libcompizconfig0 (>= 0.8.3)


My graphic setup is gory but trendy

ati radeon 4850 hd x2 proprietary driver driving 2 IBM T221 displays
with 4 DVI out @1920x2400x34Hz, custom modelines.

|1-2| |3-4|
:0.0  :0.1

1-2 form a `multi-display desktop' (and 3-4 another one)
you can't drag windows between 1-2 and 3-4 but ok
within 1-2 (excepted tearing but that's unsync hardware).

kernel 2.6.31-21-generic

Bugs are


(misbehavior of what is meant as `full screen')

- Gnome desktop bar (the Bar with Applications/Places/System ...
poweroff tray at top) reaches the topleft of 1, but stops middle of
physical screen (topright of 1) where I would like it to go topright of
2. This bug was here in previous releases.

But those have newly appeared with latest dist-upgrade:

- resizing a window with topleft in 1 shows a `wanted watermark' that
can't cross middle of desktop.

- `fullscreen' button actually makes window stitch either 1 or 2 not
encompass 1-2.

- `ring switcher' or WindowManagement `scale' will interestingly, grab
all the windows from 1 and 2 spaces, and do the animation limited to 1
or 2, not in 1-2, depending on the last active window


(minor) Not sure how to set a different background for each desktop.


(minor) resizing is awfully slow maybe 2.5sec. Ok there is lot of RAM


(rain effect) will freeze the hardware.


Informatively, I also enabled one extra virtual desktop for each
physical desktop that is properly supported by Cube and co but I rarely
use it.


Thanks for any clue,

Sincerely yours,
