Depends on the perspective :-). Lets give add some background (narrative/
spin). Some people might struggle with this; like people with epilepsy, strobe
and visual motion sensitivity. MarjE (marching ants)

Also flashing might mean lots of paint refreshes; which causes high CPU load.
It's actually 7% for basic table & a comment in it while holding the key

Pick some lovely big document and like attachment 121138 (there is table with
comment on page 1)... and CPU hammering at 25%. 

It's smooth, so you can say well nothing bad.. But well if you're on battery
this less joyful (battery drain). 

And next I jump topic the environmental dimensions. A lots energy wasted. If
you look at the individual scale this maybe, nah. But if you take into account
all users this probably adds up. [Yes, even software could/should have an
eco-label]
