Steps to reproduce:
turn anti-aliasing all the way off
turn anti-aliasing all the way on

open another window (windows key, click on something in the taskbar)
re-open minecraft (DON'T CLOSE MINECRAFT COMPLETLY)
Observe
Expected results:
smooth distant textures (file 2021-05-12 (1))
Observed results:
weird lines and flashes (files 2021-05-12 & 2021-05-12 (2))
Notes:
I first noticed this with the Addition of RenderDragon.
I use an AMD Radeon RX 5600 XT.
There are similar bug reports, but none explicitly described my problem.
the AMD software doesn't seem to override the in-game options.
