I'm trying to make a 3D editing program with a menu but when I try to paste an image on top of everything else it flickers. Does anybody know what is causing the problem?

example:
make object cube 1, 50
do
paste image 1, 0, 0
sync
loop

Sync is short for 'Syncronize' and what it does is update the 3D world and draw it to the screen.

3D and 2D screens are different entities and 3D has preference. So, if you put any text or 2D images onto a screen which already has 3D on it, at the very next Sync they will be overwritten by the 3D screen.

Try simply moving the 2D screen operations to directly after the Sync:

What TDK said was right
the reason your example doesn't flicker is because there's nothing else in the loop; your 2D command is right after your sync so you don't notice any flickering.
It's just a coincidence that you hadn't turned sync on
