Paper2D Actor becomes invisible

I have this problem during gameplay. When i play the game some blades are visible, but others flickr between visible or invisible. The gaeplay is that if i hit a blade i die. Whit this problem i can not see some of the blades but i still hit them and die. All the blades use the same blueprint.

During simulation they are all visible.

But during gameplay some are but some are not.

Render is set to visible. Same thing is happening even if i export the game. Could use some help to solve this problem.

Found a solution. Just changed the background texture to a lower resolution image.
