Here is the code.

when gf clicked
delete all of [COLORS v]
delete all of [Code v]
hide list [Code v]
turn video (on v)
set video transparency to (100)
set [starting in v] to (3)
say [Click when you're ready to record. Click again afterward to stop the recording and get your save code.]
wait until <mouse down?>
set video transparency to (0)
repeat (3)
say (starting in)
wait (1) seconds
change [starting in v] by (-1)
end
say []
repeat until <mouse down?>
Record Frame:: custom blocks
wait (0) seconds
end
Get Code:: custom blocks
define Record Frame // Run without screen refresh.
set [x v] to (-240)
set [y v] to (180)
go to x: (x) y: (y)
repeat until <not <(y) = (y position)>>
repeat until <not <(x) = (x position)>>
change [x v] by (1)
change x by (1)
Scan Color:: custom blocks
end
set [x v] to (-240)
set x to (-240)
change [y v] by (-1)
change y by (-1)
end

define Scan Color // Run without screen refresh.
set [color v] to (0)
repeat (32)
repeat (32)
repeat (16)
if <touching color (color)> then
add (color) to [COLORS v]
stop [this script v]
end
change [color v] by (16)
end
change [color v] by (1792)
end
change [color v] by (458752)
end
define Create Code // Run without screen refresh.
set [code v] to ()
set [frame idx v] to (1)
repeat (length of [COLORS v]
repeat (172800)
set [code v] to (join (code) (join [,] (item (frame idx) of [COLORS v]))
end
change [frame idx v] by (1)
end
add [Your code is:] to [Code v]
add (code) to [Code v]
add [Triple click to copy.] to [Code v]
show list [Code v]

There are 2 problems.
1.) It's very laggy. It's probably the run without screen refresh blocks, but there's no real workaround I can think of.
2.) When you end the recording, it doesn't give you the code. I have no idea why, and this is the main problem. Can someone tell me what's wrong and how I can fix it?
EDIT: The glitches were fixed!

Can you share and link the project we can see the issue happen? Also, I've made a project called screenshot engine, and I've optimized it as much as I can, and you might be able to use it for this.

Sure, linked here.

Glad you found an answer! Since this is resolved, I'll close it to help highlight the answer and prevent future responses. If you need it re-opened, though, you can report this and ask.
