When scrolling through CIQ Glances, there is quite a lag until the glance contents a drawn so you just see the glance/app name for a bit. Other watches draw the glance views much faster so you can see their contents almost (if not) immediately.
This has a low quality feel to it IMO, especially since much cheaper watches don't have this issue.
It is more pronounced with more CIQ glances/apps installed. I have 12.
