A clear and concise description of what the bug is.

When running gzdoom on the Plasma-Wayland desktop, most input keyboard events are ignored. This is because gzdoom calls SDL_StartTextInput mode at the beginning. Note that the documentation for SDL3 says "On some platforms using this function shows the screen keyboard and/or activates an IME, which can prevent some key press events from being passed through." Maybe this is also true for SDL2, though not documented.

I attached a patch, which fixed that issue on my system:

Steps to reproduce the behaviour.

Explain how to reproduce

1. Start gzdoom on a Linux Plasma-Wayland system
2. Start any game (e.g. Ultimate Doom or Doom 2)
3. Try to move using the WASD keys; they will be ignored.
