Commit f112ba03bbd6072df9f8879bb231f7f0abb14d2e "radeon: Use upload manager for buffer downloads" is causing corruption in the game Starsector with my A10-5700. Not observed in other applications yet but not extensively tested yet.

In the game, there is a visual effect of electrical arcing over the enemy ship when hit with an weapon with EMP. However starting with this commit triangles of the effects base colour are rendered over entire screen from source location. Even when game paused, triangles are still randomly flashing away.

Reverting the commit resolves the issue.
