weird flahing browser bar Rated 2 out of 5 stars

It seems like a great ext, but i am getting a werid flashing / reloading issue when i try to split the far right tab in a long list of tabs.
I am using the Pimp-zilla theme and three or four rows of all the toolbar icons show up at the top of the split window

So, this seems like a great ext, but not workgng well for me.

Oh yeah, i have my browser.tabs.closebutton setting set to '2'
