Bug Description

When using Unity with two windows of the same size open, activating compiz's 'scale' causes inconsistent padding at either sides of the screen. This is because the scale plugin does not factor the Unity launcher's width into the calculations; therefore, the left edge of the screen has less padding than the right edge.

The problem detailed with measurement: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/766191/+attachment/2457195/+files/pic1.png

I think scaling should be done considering the screen width minus the dock width.

This may seem very tricky to pull out since scale is a compiz plugin and so on, but, again, like it is and when windows get under the dock, it feels strange.

Cheers.

I can't reproduce this. Is this bug 100% reproducible ? And are you running Unity with the latest updates? Thanks!

I've a little patch to make that scale plugins considers the whole screen minus the launcher size. I've some problems with terminal windows, it seems to work well with all other windows.

Two nautilus windows without the patch... http://people.ubuntu.com/~andyrock/prova2.png

As you can see with nautilus windows (and all other app i've tried expect gnome-terminal) not only the launcher area is not considered, but the spacing beetwen the launcher area and the first window is the same of the space between the last window and the right edge of the monitor.

With gnome-terminal windows the launcher area is not considered but the two external spacing are not the equal.

------------------------------------

@smspillaz any idea about the gnome-terminal problem?

P.S.: should not be so difficult update the launcher area when launcher icon size change in unity.

This should be a low-priority bug as this really is a small visual problem (that should be addressed, admittedly). It still affects up to 12.10 (though I have not tested 13.04 nightly).
