Any known issues with WordPress 3.7.1?

Hi there, it would be really helpful if any of you could give some insights on this...! It seems that since I've updated the WordPress version to 3.7.1, many of the issues started to happen with admin site. Text box goes all white on edit post page so cannot see the texts, images won't load fast & takes ages to respond so ends up failing, even the actual site is very slow responding so sometimes the sliders won't load properly etc... Different platform, browsers didn't help at all. Is it just the respond time issue of the hosting server??
