Objective

Solution

  • Do not cull nodes with a rotation, but don't do proper culling in this case

As a reminder, changing rotation and scale of UI nodes is not recommended as it won't impact layout. This is a quick fix but doesn't handle properly rotations and scale in clipping/culling. This would need a lot more work as mentioned here:

// Calculate the effect of clipping
// Note: this won't work with rotation/scaling, but that's much more complex (may need more that 2 quads)
