--- Comment #4 from Timothy Arceri t_arceri@yahoo.com.au --- This looks like an issue with compat profile which until recently was limited to OpenGL 3.0 (radeonsi now supports 3.1). You seem to be working around it by forcing a lower GLSL version. Recent Wine versions now use Core profile when they detect Mesa, either way I don't think this is a Mesa bug.
Future Mesa version will likely support higher compat versions, but Apps (and Wine) need to properly check supported features.
