Windows sends an extra left control key up/down input event for every right alt key up/down input event for keyboards with international layout. Since commit 830473455f ("ui/sdl2: fix handling of AltGr key on Windows") QEMU uses a Windows low level keyboard hook procedure to reliably filter out the special left control key and to grab the keyboard on Windows. The SDL2 version 2.0.16 introduced its own Windows low level keyboard hook procedure to grab the keyboard. Windows calls this callback before the QEMU keyboard hook procedure. This disables the special left control key filter when the keyboard is grabbed. To fix the problem, disable the SDL2 Windows low level keyboard hook procedure.
