animation - If browser fails to generate frames on time for displays, On which side dropping of a browser frame happens? -


i have been trying understand critical render path of browser quite future seminar. understand process, there 1 thing that's bugging me. hearing frame dropping quite lot.

i understand device refreshes screen 60 times in second (60hz). browser has generate 60 frames in second smooth animations. browser gets 16.7 ms(mostly 10-12ms) generate frame.

so, if browser fails generate frame under 16.7ms, frame go? still displayed on screen?

if still gets displayed, frame drop mean missing 1 of device refresh slot right??

so, example if browser generates 15 frames in second , feed display of device, device displays 15 frames since frame rate low , missing 45 screen refresh slots, user of device can recognize jank.

is above explanation correct?
