What you did

Ran the anti_aliasing example with cargo r --example anti_aliasing. Then minimize the window, then restore the window.

What went wrong

No more shadows!

[andriyDev]

Possibly related to #23991 or #24149.

[andriyDev]

Tested on 0.18.1. Shadows exist after minimizing and restoring the window.

Looks like if I use DX12, minimizing the window just completely crashes (on main)!

The crashing for DX12 seems to have been noted before in #23399

The shadows disappearing looks to be vulkan specific then possibly?
