I've noticed the same problem, like code below.

Code:
#include <acknex.h>

function main() {
	
	vec_set(sky_color,COLOR_BLUE);
	video_set(200, 200, 32, 2);
	
	level_load(0);
	
	you = ent_createlayer(SPHERE_MDL,0,5);
	vec_set(you.blue,COLOR_RED);
	you.x = 25;
	
	while(1)	{
		sun_angle.pan += 10 * time_step;
		wait(1);
	}
}

But in A7 works very well:
