Not really everything. It really doesn't solve the "problem" (feature?) of the upper bar and the extentions icons becoming obnoxiously big and intruding. Has anybody this problem too? http://i.imgur.com/UKWcwTG.png
I mainly use opera for loyalty, and because actually I don't dislike the speed dial + stash method.
But I also enjoyed the nice design.
Now there is this huge bar, with usless spaces, instead of a more scaled one.
And no workaround here suggested fixed it.
Has anybody been succesfull in resizing the UI and not just the text/pages sizes?

I've started having a very big problem since the silent update to Opera23, I'll try to see if disabling hardware acceleration works.

Here's what happen: when I close a tab with the ctrl+w shortcut, about 2 times out of three, the whole browser restarts.

Very annoying since I have a bad connection and often leave a tab to load in background while I read something on a lighter page (e.g. video loading in background while reading a blog)

Has anybody experienced the same problem?

Latest stable version still didn't fix the problem.
I hate having to open another browser just to post a comment.
