Media & Text Slider srcset question

Hello Getwid Team!

Thank you for the plugin, we use it on many websites. It’s really handy and usually working very well.

On a new website we are building at the moment (not public yet) there is a sligthly odd behaviour of the Media & Text Slider. When scaling down the screen to below 768px the slider seems to display a very blurred image, probably the one defined for 120px within the srcset of the slider.

Is there any way for a user / developer to change the srcset-settings or to define which sizes should be uploaded and displayed at what width? It seems that Getwid is rescaling and custom-saving images for the srcsets (ie the image upload sizes are not the one defined by the system?)

Any tips and help is greatly appreciated! Thanks very much!

Peter
