Unit Test Sessions window menu fonts

All menus in Unit Test Sessions window look smaller and have different font than all other menus of VS. Below are the screenshots, first one is a menu from Unit Test Sessions, and second one is how I would expect a menu to look. Before I fully reinstalled the system menus were looking good, but now I cannot find the options to set them up. How can I do it (might be relevant that I have a system wide scaling to 125%)? 
Thank you.
