This happens only if you use <fieldset>
with <legend>
- without it the corners render ok.
You can fix this bug by applying display:inline
or display:inline-block
to your <legend>
element - but than you have to reposition it back in place by setting position:relative
and moving it around.
Depending how the styling of your legend looks like (with background it will look the same - without the background the border of fieldset will still be visible behind the letters) you can make it look pretty much the same as in other normal browsers.
