### System information

Godot v4.1.stable - Windows 10.0.19045 - Vulkan (Compatibility) - Intel(R) HD Graphics 4600 (Intel Corporation; 20.19.15.5126) - Intel(R) Core(TM) i3-4330 CPU @ 3.50GHz (4 Threads)

### Issue description

When I try to join 68 images of 128x128 resolution in an atlas it returns a transparent 1x1 image

I tried using few images and it doesn't work either

It doesn't work either with 16x16, 32x32, 64x64 resolutions
