Hello, Well, I got this bug as well and can reproduce at will, on a vaio pcg- z1rmp, based on an ATI Radeon Mobility M6 LY.
I tried many things unsuccessfully until... until I found the bug or so I think. Here is it : One line is missing in the HumanCircle.xml file Here is a part of that file : <!-- password box --> <item type="rect"> <pos x="50%" y="50%" width="box" height="box" anchor="c"/> <box xpadding="0" ypadding="0" spacing="5" orientation="vertical"> <item type="rect"> <pos x="0" y="0" width="box" height="box" expand="true"/> <normal color="#ffffff" alpha="0.3"/> <box xpadding="50" ypadding="15" spacing="10" orientation="vertical"> <item type="label" id="pam-prompt"> <pos x="0"/> <normal font="Bitstream Vera Sans Bold 18" color="#523921"/> <stock type="username-label"/> </item> <item type="rect"> <normal color="#523921"/> <pos width="160" height="24"/> <fixed> <item type="entry" id="user-pw-entry"> <pos y="1" x="1" width="-2" height="-2" anchor="nw"/> <normal font="Bitstream Vera Sans Bold 14" color="#000000"/> #<---here is the missing line </item> </fixed> </item> I pointed out the line I added that shoult be between lines 98 and 99 in the original file. Sorry about that : I still lack some skills in Linux dev to produce a patch file. I hope it'll come (soon ! :-)) i set a 14 points font size because it feet my 1400x1050 screen, but a tinier font would probably suit better. I don't know about others Themes but it may be good to have a look in their conf. file as well.
