When you navigate to any /explore[showcase] page directly (refresh page if navigate from /explore) and then click on header logo to navigate to index page, then blink on parent route component happens. This one component https://github.com/nuxtlabs/vue-telescope-website/blob/dev/pages/explore.vue#L3
Apparently v-if="!$route.params.showcase || ($route.params.showcase && !directHit)" this conditions is firing differently than in Vue 2.
