It’s in the title. If a game uses a custom cursor and then a player joins then leaves the game, that custom cursor will still be present in the Roblox home screen on the Roblox Desktop app.
This is happening to Studio too, if you move out of the workplace tab, the mouse will stay on the last position and will only return after clicking IN the workplace tab.
@RodotIV we will investigate soon, given this thread has not been looked at in a while we would like to know if the issue is still reproducible/relevant by you?
