What you did

• Run cargo r --example anti_aliasing.
• Minimize window.
• Restore window.

What went wrong

The shadows "flicker" for one frame - they stop rendering for one frame and then start again. It's hard to get a video of this even because it happens so fast.

Additional information.

This is a followup to #24162, which was somewhat fixed, but it's clear this is still an issue.

@JMS55 since you already have context here.

Also @alice-i-cecile is this worth putting in 0.19? I think it's shippable without fixing this, it just looks unpleasant, and is a regression.

Sounds like a system ordering issue.
