    I didn't change anything packaging side in the last days, so it should be a mesa issue. Please open a bug on freedesktop.

      The problem seems to extend over to Chromium/Firefox as well as Steam. The about:gpu shows the following. It seems to effect more then just Steam. Can anyone confirm?

      Code:
      Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable

      Firefox's about:support shows a similar problem.

            I have the same problem as the other posters on OpenSUSE + Pontostroy repository, so we can rule out a packaging problem.
            I also use Nouveau, so this is not only related to Radeon.

            Code:

Error: OpenGL GLX context is not using direct rendering, which may cause performance problems.
            But I can start a game and it does seems to be using hardware acceleration.
            Probably the most annoying thing is that I also get a blinking/flickering cursor :<

            Sorry for posting here while not using your PPA, I just wanted to confirm that it's not packaging/radeon related.

              For firefox you need to manually enable MOTC for OpenGl composting since version 28 even if the driver is working

                Guys with the GCC error, that is Steam's fault.

                Steam is shipping an older version of a lib than your Mesa was compiled against, and forcing it to be loaded. This obviously breaks.

                Solution: remove Steam's version of that lib, use your system's version.

                  Can you explain how to do that?

                    I just found a workaround

                    The problem is "libgcc_s.so.1" asking for GCC4.7. I've got direct rendering working fine, it's just steam being awkward because of this library. If you run steam in a terminal but in future do something like
                    Code:
                    steam | grep error > steam-errors.txt
                    you'll get a nice text file in the directory you're in (default: home folder) to see what's up.

                    Here's the error:

                    libGL error: dlopen /usr/lib/i386-linux-gnu/dri/swrast_dri.so failed (/home/ant/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1: version `GCC_4.7.0' not found (required by /usr/lib/i386-linux-gnu/dri/swrast_dri.so))
                    libGL error: dlopen ${ORIGIN}/dri/swrast_dri.so failed (${ORIGIN}/dri/swrast_dri.so: cannot open shared object file: No such file or directory)
                    libGL error: dlopen /usr/lib/dri/swrast_dri.so failed (/usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory)
                    libGL error: unable to load driver: swrast_dri.so
                    libGL error: failed to load driver: swrast

                    so locate where another libgcc_s.so.1 might be on your system:

                    Code:
                    locate libgcc_s.so.1
                    I'm on a 64bit install, steam runs 32bit, so of the results i just went with /lib/i386-linux-gnu/libgcc_s.so.1.

                    So to solve the problem, i just copied this file to replace the one steam was using:

                    Code:
                    sudo cp /lib/i386-linux-gnu/libgcc_s.so.1 /home/ant/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1
                    (you could symlink which might be more(?)resistant to the steam client being updated, but the nature of this problem is that it will be fixed shortly when valve update the library. I'm also not as comfortable with symlinking as replacing )
                    Assuming you're in a similar situation, the above command with your own username instead should fix it right up.

                      That totally worked for me, I can now enjoy artifact free dota 2!
                      Thank you, you've been really helpful!
