Problema de movimiento Tropico 4 (57690)

Jugue Tropico 4 A través de Proton, todo funciona excelente, a excepción del movimiento por el mapa, ninguna tecla de las flechas las toma, todas las demas funciona excelente, pero la del movimiento no las toma, y toca moverse por el mapa con el Mouse, cosa que es incomodo.

Google Translate: [...]everything works excellent, except for the movement on the map, no arrow keys take them, all the others work excellent, but the movement does not take them, and it is time to move around the map with the Mouse, which is uncomfortable.

No source file, test, or entry point is identified. Start by reproducing Tropico 4 through Proton on the reported Manjaro setup and verify whether arrow keys fail while other keys work; done means map movement responds to the arrow keys.
