Hello,
Thanks for screenshots. As you can see on our new demos and in the changelog, XStore 5.0 beta has been rebuilt from the scratch, so theme got better speed results and changed styles.
Please check new settings in Theme Options, there more settings for Shop and our Variation swatches https://www.youtube.com/watch?v=XO-PDvhPypc&index=8&list=PLMqMSqDgPNmCCyem_z9l2ZJ1owQUaFCE3
Also, if you want something more, custom css code can be used. We are ready to help with custom css.
Let us know if you need any further assistance.
Regards
