This is a regression introduced by:

kernelbase: Use conhost to handle Unix consoles.

The conhost-related terminal output is "fixme:conhost:screen_buffer_ioctl
unsupported ioctl 50402c" but I'm not sure whether it is relevant.

Steps to reproduce:

1. Download "RPG Maker VX Ace Run Time Package" from
https://www.rpgmakerweb.com/run-time-package
2. Unpack "RPGVXAce_RTP.zip" and run "Setup.exe"
3. Download the game from https://www.freem.ne.jp/dl/win/7629
4. Unpack "Capella_1.09.zip" and run "Game.exe"
