GML Game Jitters?

Heya! I've been working on my project and I've had this problem for a bit.
I've tried everything I could think of but none of them worked. My problem is when the player jumps, the jump looks really Jittery. The parallax background is also Jittery when the player moves, when the player stops in snaps to the player.
If anyone knows the fix to this please let me know!!

Code:
///React to inputs
scr_get_input();
move = key_left + key_right;

//Move Right
    if (move == 1)
    {
        hspd += acc;
        if (hspd >= maxspeed) hspd = maxspeed;
    } else if (hspd > 0)
    {
        hspd -= acc;
        if (hspd <= 0) hspd = 0;
    }
//Move Left
    if (move == -1)
    {
        hspd -= acc;
        if (hspd <= -maxspeed) hspd = -maxspeed;
    } else if (hspd < 0)
    {
        hspd += acc;
        if (hspd >= 0) hspd = 0;
    }

//Running
if key_run
{
    maxspeed = 3;
} else if !key_run
{
    maxspeed -= 0.1;
    if maxspeed < 2 maxspeed = 2;
}

//Gravity
if (vspd < 10) vspd += grav;

if (place_meeting(x,y+1,obj_solid))
{
    if (key_jump)
    {
    vspd = -jumpspeed
    audio_play_sound(snd_jump,5,false)
    }
}

if (vspd < 0) && (!key_jump_held)
{
    vspd = max(vspd,-jumpspeed/3)

}
Background Parallax
Code:
//Horizontal Parallax
background_x[0] = floor(view_xview/1.2);
background_x[1] = floor(view_xview/1.4);
background_x[2] = floor(view_xview/1.6);
background_x[3] = floor(view_xview/1.8);

//Verticle Parallax
background_y[0] = floor(view_yview/1.2);
background_y[1] = floor(view_yview/1.4);
background_y[2] = floor(view_yview/1.6);
background_y[3] = floor(view_yview/1.8);

How are you drawing the player? Make sure you round or floor the coordinates before drawing, as drawing at sub-pixels may introduce blurring or distortion.

No, draw_self is a function that draws the instance, the same way that draw_sprite is a function that draws a sprite. You need to tell it which sprite to draw. Presumably, you can get that with sprite_index.

Looks like it works fine now! No more jitter for the player, thank you so much!!
All I need to do now is figure out the background bit
