[Solved] Odd thumbnail Behaviour

Forgot to say, that the fault can be recreated on a desktop by dragging the browser window in, so it has the same dimensions as a mobile/tablet. As you do so you can see the thumbnail resize going from good to bad. 

@radiostv,

Try the CSS code below:

@media screen and (max-width: 800px){
   #wpforo-wrap figure[data-attachids] {
      width: auto;
   }
}

The CSS code should be added in the "Custom CSS code" textarea, located in the Dashboard > Forums > Settings > Style Tab.  

Please don't forget to delete all caches and press Ctrl+F5 (twice) on the frontend before checking to reload the updated CSS file.   

Also, please try on incognito mode if you're checking on mobile devices. Because mobile browsers have a hard cache, you'll not be able to see the change immediately.
