Shader issue.

[denizdeni]

my code on Draw Gui:

if(waveydraw) {
var_time_var += 0.04
shader_set(shd_wave);
shader_set_uniform_f(shader_get_uniform(shd_wave,"time"), var_time_var);
shader_set_uniform_f(shader_get_uniform(shd_wave,"mouse_pos"), 0, 0);
shader_set_uniform_f(shader_get_uniform(shd_wave,"resolution"),  __view_get( e__VW.WView, 0 ),  __view_get( e__VW.HView, 0 ));
shader_set_uniform_f(shader_get_uniform(shd_wave,"wave_amount"), 5);
shader_set_uniform_f(shader_get_uniform(shd_wave,"wave_distortion"), 80 );
shader_set_uniform_f(shader_get_uniform(shd_wave,"wave_speed"), 2);
application_surface_draw_enable(false)
better_scaling_draw_surface(application_surface,0,0,1,1, 0, all, 255, true)
shader_reset();
}

Normally, it's looking like

If i set waveydraw to true it's looking like this.

why????

For the sake of context, what are you expecting to happen instead? Please always include your expected scenario so that we can know how what's going on differs from what's intended. Undocumented code and two screenshots don't exactly form a solid basis to diagnose problems on.
