@benjaminst,

This is just a small CSS issue with the theme or other plugins. Please leave some example URL to allow us to debug the issue. 

@benjaminst,

Use the CSS code below to solve the issue:

#wpd-bubble-wrapper>#wpd-bubble #wpd-bubble-add-message, .wpd-inline-form-wrapper{
   max-width: none;
}
@media screen and (max-width: 1024px){
   #wpd-bubble-wrapper.wpd-right-corner>#wpd-bubble #wpd-bubble-add-message {
        left: auto;
   }
}

Put the code in the Top Admin Bar > Customize > Additional CSS > "Additional CSS" textarea, save it, delete all caches and check again.

Please don't forget to press Ctrl+F5 (twice) on the frontend before checking.
