OpenGL GLX error

[andax]

I get this error every time I start steam client:

OpenGL GLX context is not using direct rendering, which may cause performance problems

Status changed to 'Confirmed' because the bug affects multiple users.

[Damian Christey (damian-christey)]

Same here. Worth noting the output of glxinfo | grep render :
direct rendering: Yes
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Gallium 0.4 on AMD KAVERI
    GL_MESA_texture_signed_rgba, GL_NV_conditional_render, GL_NV_depth_clamp,
    GL_NV_blend_square, GL_NV_conditional_render, GL_NV_depth_clamp,
    GL_OES_fbo_render_mipmap, GL_OES_get_program_binary, GL_OES_mapbuffer,

Steam runs fine if I switch to the proprietary fglrx driver.

Same, here.

I can't change to the proprietary drivers, unfortunately:

This workaround http://askubuntu.com/a/538907/22153 works with Radeon open source drivers.
