I have problem exporting projects on my own android device: screen flickers like hell.
It seems related to screen buffer: scrolling content up and down, I can see some old ghost frames. It looks like .

As an example, think about a black background and a horizonal white line: moving the line up or down the screen displays 3 flickering white lines .

My device runs Mali-T880

Instead, exporting to Nox Player it works pretty well.

Isn’t it weird? How can I solve it?

The issue

Symptoms look as some frames are not computed (not initialized, not redrawn), but still exist whitnin video buffer, thus displayed.

So I ended up solving this issue forcing nodes to update each frame, putting following code in main node:

  func _process(delta):
	for i in get_children():

It looks an engine bug to me.

This has been an issue for me as well.

May I ask what is in your update() function?
