Symptoms

Game's movie player relies on recent bit in GetAsyncKeyState to detect keypresses (e.g. if ((GetAsyncKeyState(VK_ESCAPE) & 1) != 0)) and these proton hacks interferes so movies cannot be skipped or paused:
4b7342236aedf9db88dcdebd251889262a93505f -> HACK: user32: Always pretend that GetAsyncKeyState recent bit is 0
c8355ba22826e2e492059b7d6eba729f7e3e1256 -> HACK: win32u: Enable GetAsyncKeyState() recent bit for Amerzone (1999).
