01:14:253 - in stable, the slow SV on the spinner makes it fade in from behind the finisher, but in lazer (because devs don't care about fixing taiko) the spinner is visible as it crosses the entire screen (from 01:05:775 - 01:14:253). It's visually distracting and that could be intentional (e.g. gimmick and SV maps mess with visuals all the time) but if you wanted the map to play similarly on both version of osu, a possible alternative is to crank the spinner's SV to be as high as it goes (although it really shouldn't be your job to fix it since it's a problem with lazer, not your map)
