Recently, the site stylesheet seems to have been modified to include:
width:100% causes the user's name and score to appear under their icon, rather than next to it:
width:100% disabled, the panel is the same as it always used to be (and, I assume, as it is supposed to be):
Can anything be done about it aside from patching the CSS?
N.B.: I am using Opera 12.17, which is unfortunately unsupported by its own publisher and is now about 3 years without any major updates. This is the same as IE 10, however, and in my opinion sites should not break previously working functionality for browsers of this age.
