Issue with the tab strip component

I am encountering a bug with the tab strip having a glitched background with random screen elements. It happens every time the client reloads(when I start the client or when I save and publish in the designer). It fixes itself when I mouse over the element, but it’s still very annoying.

Is there any way I stop this bug from happening?
