This is happening due to width restiction we have on Company Name in main.CSS -
.top_bar .logo {
font-size: 1.67em;
font-weight: 600;
height: 100%;
margin-left: 1em;
padding-top: 0.33em;
max-width:20em;
}
What you can do is add custom.css under Content\CSS folder something like this -
.top_bar .logo {
max-width:30em;
}
This will override porperty on main.css and will aloow you wider Comapny Name. But beware that for lower resolution (1024x768) this might break you top bar.
