Opera 12.14 strange google display

Ever since version 12.14 of Opera, on few sites I get their menus displayed incorrectly.
Google search page, for example, puts the words on the left, vertically into a narrow column, like this.

The strange thing is that a button "Fit to Width" repairs the display, the usual google black bar with words gets filled.

This makes no sense to me. Might there be a more relevant way than Fit to Width to get the display correctly right away?

I'm on XP-SP3.

 

Bump
I hate doing bump, but I believe there are Opera users here who might be seeing a similar silly looking display.

 

I wouldn't care about reporting bugs (except vulnerabilities) of Opera now. It's a bit irrelevant - Opera will soon get a major rewrite:

- http://my.opera.com/haavard/blog/2013/02/13/webkit

 

Which is months down the road if they even manage to get it out this year. You might as well report bugs while it's still supported. All it is is a throwing in the towel move anyway.

 

I finally figured it out.
Google didn't like user agent. I had to change it to pretend it's Internet Explorer instead of the normal Opera I've been using for years.
Google also used iframes, but that they will not get from me.
I can't really read source, but a bunch of script statements are of the sort 'if it's Chrome - display...' otherwise display blank. At least that's what I think I see. But that doesn't really match the fact that Seamonky was ok. So I don't really know what's going on and it probably doesn't matter at this point.
