Looks like a bug in Kivy. Reading https://kivy.org/doc/stable/guide/inputs.html, it looks like Kivy reads input on GNU/Linux by accessing the input hardware directly (see ProbeSysfsHardwareProbe), bypassing all window management, which would explain that behavior. So I can only conclude that Kivy is currently not suitable for developing applications for GNU/Linux.
