Comment 11 for bug 1057120

OK, I've been testing the Lubuntu Quantal 20121014 i386 image intensively on two sets of hardware, but I have not tested at all in a VM.

On my old VIA C7 w/P4M800 graphics I can NOT reproduce this regardless of whether I choose Try or Install from the boot menu.

But on my Intel Atom 230 w/Intel 82945G/GZ Integrated Graphics this behavior is easy to reproduce only if I choose Install from the boot menu. If I begin from the live desktop I can't reproduce the behavior on this hardware.

It would therefore be interesting to know exactly what graphics chips are effected by this bug.

Regardless the installation does complete successfully if you simply disregard the "window-over-window" behavior.

From a testing perspective try this to see if it can be reproduced:

(1) Boot the live CD, select the preferred language, and then select Install

(2) Select your preferences on the first two installer windows. (I've only tested in English and with DL updates/do install 3rd party selected)

(3) On the third window where you select the type of installation see if you can "drag" that window and recreate this screen "blur" behavior.

Note: If choosing advanced partitioning the "window-over-window" behavior will be quite evident even w/o dragging a window.
