Is there anyway to get rid of Aura

[Bubba]

I was playing around with Bg Aura, and I noticed there is NO way to get rid of it. I paused, put Block all over the screen, erased the Block then erased The empty part, it was still there.
Then I made a tower of powder that was 1 dot wide and it did not collapse.
So evan if there is no air on the screen, Aura CAN NOT be destroyed, the only known way is to reset.
Do you guys know of any ways to destroy Aura?

Does switching to another background, creating a vacuum, and switching back to Aura work?

[Qwerty]

Creating a vacuum, meaning using the right-click air?
