Dinosaur stops jumping when a cactus appears on screen

I noticed that the dinosaur stops jumping when a cactus appears on the screen, even when the activation is above 0.55. Since the whole purpose of the game is to jump cactus, this doesn't allow the program to work properly. I wonder if this has something to do with hardware limitations, because the appearance of the cactus can demand more processing. Any help is welcome

Start by reproducing the behavior while a cactus appears and trace how the activation value is calculated and how jumping is triggered. The issue provides no file or test location; done means the dinosaur still jumps over cacti when activation is above 0.55.
