[Mesa-dev] [PATCH] radeonsi: update hack for HTILE corruption in ARK: Survival Evolved

[Samuel Pitoiset]

It appears that flushing the DB metadata is actually not sufficient
since the driver uses the new VS blit shaders. This looks quite
strange though, but it seems like we need to flush DB for fixing
the corruption.

Fixes: 69ccb9dae7 (radeonsi: use new VS blit shaders (VS inputs in SGPRs)
