Of course there is an interaction. You have a stack of software, all
listening for keystrokes. They will have a chance to handle them in
roughly this order:

1. your kernel (typically handles Ctrl+Alt+F1..F10 to switch TTYs)
2. your X server (in older times, it would terminate on
Ctrl+Alt+Backspace; also keyboard layout switching happens here)
3. your window manager or desktop environment (Alt+Tab window
switching in GNOME/Xfce/KDE, any i3 bindings, any desktop-wide
shortcuts such as Volume Up or Launch Web Browser)
4a. the actual application if it is a GUI-based one
--- or, for terminal-based applications: ---
4b. your X terminal emulator (GUI terminals may have some bindings to
display their help, activate their menu bar, open, close, or switch
5. your terminal multiplexer if any (GNU Screen takes Ctrl+a, Tmux
takes Ctrl+b by default)
6. the actual terminal-based application running within the stack

I predict that your issue is not caused by hardware.
