Steps to reproduce
Run the project, select WebGL2 in the settings, and run it—everything works fine! (green in the screenshot)
Then select WebGPU in the settings and run it—some objects aren't displayed. (orange in the screenshot)
I've pointed everything out in the screenshots.
Observed result
Some items are not displayed
Expected result
Everything should be displayed.
