Priority: medium Bug ID: 58840 Assignee: dri-devel@lists.freedesktop.org Summary: rendering error with MSAA on HD6850 Severity: normal Classification: Unclassified OS: All Reporter: aaalmosss@gmail.com Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
There are weird rendering errors when OpenGL applications use MSAA framebuffer. The output is mostly noise. KDE 4.8 with OpenGL compositing is totally unusable this way.
It is also interesting, that MS visuals are only advertised in glxinfo, if I have the msaa-capable r600_dri.so installed on the system. If I only enable it via LIBGL_DRIVERS_PATH and LD_LIBRARY_PATH, they are not advertised, but still selectable. At least with __GL_FSAA_MODE=4 the applications are broken in the same way.
