I can confirm this bug on multiple Kirikiri2 games, on the latest 2.14 version of WINE. It occurs with and without staging patches. (I'd include the requested log output, but it's pretty much identical to what has been provided, minus version numbers and directory names)
EDIT: Forgot to clarify: I'm using a full, purchased version of the game.
