4.9.1 thumbnail image size

After upgrade to v4.9.1 I have found that the thumbnail images size were changed.

using Divi and your widget is inserted into a Divi sidebar module.
In previous version 4.8.5 image size was set in widget parameters as 800×532 but the upgrade changed its proportions and the result is narrow and tall.
I changed the parameters to 300×266 but the frame around it is too big and I can not find a way to change its margins.

How do I control the margins of the thumbnail?
thanks
