Affiliate panel breaks the layout of Home screen

Affiliate panel breaks the layout of Home screen if the browser window is too narrow. This usually happens if the affiliate uses other language as the default English (en-US) one.
The problem is that the Traffic Overview is wider as by default and it is not possible to set the right width automatically.
 
You can set the right width in your affiliate templates by adding a new property 'min-width' into the .SingleMode class 
 
in Merchant panel > Configuration > Design > Affiliate panel theme tab > Edit theme > search custom.css and add there a new line:
.SingleMode {min-width:1100px;} /* 1100px is only an example */
