Comment 118 for bug 734908

I can confirm.
Ubuntu 12.04, Radeon graphics card, single monitor.
In my case chromium was not affected and Eduards workaround described in bug 958353 works.
Having 2 accounts logged simultaneously I removed buggy behaviour for both of them.
However:
In the first account in the same time when this bug appeared my launcher icon size (horizontal size) has changed and became bigger. It become smaller again after workaround.
In the second account launcher icons stay bigger (it's ok for me). When applying workaround I had to type password blindly as Eduards described for the second account, but for the first account screen become black and a proper password window appeared.
I have no idea what triggered this bug.
After it appeared it was permanent in both accounts until now, I promise to play with it when it appears again.
By the way, is it possible to change launcher icons size (intentionally)?
