Animation speed in variations (analysis page)

piece animation in the variations is not smooth
while scrolling a game no problem, but scrolling a variation is laggy

is this happening only to me?
pieces are going to squares in two steps (only in variations)
fyi my animation speed setting is at fast
pls dear developers, open any computer analysed game and click a variation and scroll

i tried piece animation "none"(none is faster than fast!!) now problem solved
sorry for forum pollution :3

"None is faster than fast"

Hahahahahahahahahaha.
