Vera UI7: Browsing between many of the UI pages, for example from the device control to the "advanced" sub-menu, the page first scrolls into view beyond TOP, then scrolls back until it (finally!) comes to a halt a the top of page.
The eye tries to capture content - but can't because things are moving. And then they stop. And then they are moving back...
I find that this causes extreme eye-fatigue, and the programmer who thinks that this is an "OHHH-SO-COOOL" thing to do should be chained a to a chair and forced to watch that "Creation" for some hours. He/she will be cured. Guaranteed.
