`Text2dBundle` is not frustum culled #13391

Open rparrett opened 2 weeks ago

Bevy version

What you did

Modify the many_sprites example so that Text2dBundle is used instead of SpriteBundle.

What went wrong

Logging shows that without manual intervention by the update_text_aabb system, all of the texts are considered "visible" and the framerate is poor.

With the update_text_aabb running, the off-camera text is culled and the framerate is good. It seems that adding an Aabb to the texts is enough to make frustum culling work.

There may be a better in-system solution than adding a separate update_text_aabb system, but I haven't looked into this.
