Description

The sample qualifier appears to not be working properly when used inside an interface block and seems to affect all Radeon products. This driver bug makes SSAA look like MSAA when used. Disabling the usage of interface blocks for Radeons when SSAA is enabled should do the trick, or just always disable it like in DuckStation.
