Source: higan
Version: 094-5
Severity: important
When using higan with an OpenGL 3.3 capable Gallium3D driver, it fails the OpenGL version check introduced in check-opengl-version.patch.
When I build higan from the vanilla source, it runs fine with OpenGL backend.
I'm guessing the glVersion is returning the compatibility context version rather than the core one?
Graphics card on this system is a RadeonHD 4550, and another system with an 8400GS also has this issue when using nouveau.
