That's the DRM level bugfix for use after free on async updates for plane
framebuffer swaps. It actually hurts performance rather than helps it.
There's a fix that allows framebuffer swaps again being developed right now
with some patches in dri-devel:
https://patchwork.freedesktop.org/series/57524/
You'd have to revert
"drm/amd/display: Skip fast cursor updates for fb changes"
as well though to actually allow this series to work.
