Convert all Line2D nodes on Viewport into a single Sprite node to improve performance

I am making a doodle app in Godot for mobile
I am now using Line2D nodes to make vertex from current mouse possible to previous mouse position
But soon the game gets laggy and frame rate drops down to 15-20 FPS
So I came up with an idea to save the texture of the viewport after creating those lines and then deleting the lines
I thought of applying the texture to Sprite2D but the Sprite starts flickering after doing that…

Any other idea for increasing the game’s performance would also do…

Please help!!!
Thanks in advance!!
