Thanks, but though this particular message may have been removed, it was
just an example. I'm asking about such messages in general :)

With git pickaxe, it looks like that code was removed since Mesa 12.0.6 with commit \
b639ed2f1b170d1184c6d94c88c826<wbr>c51ffc8726.   So if you upgrade Mesa, you \
won&#39;t see that message any more.<span class="HOEnZb"><font color="#888888"><br> \

            Hello.<br>
            I enabled KHR_debug to find the cause of some bugs in my app,<br>

            interested in performance-related messages that were getting<br>

            Example:<br>
<br>
               &gt; Multi-LOD fast clear - giving up (2048x16x11)<br>
<br>
            I&#39;m interested in improving my code to remove such warnings, as \
                all<br>
            extra performance is welcome. But I understand most of those<br>
            messages<br>
            only partially - e.g. in the above example I understand what it<br>
            means,<br>
            but not what might cause it or how to fix it.<br>
<br>
            Is there any documentation on such warnings?<br>
<br>
            Note that I&#39;m mostly interested in the warnings produced by the<br>

<br>
<br>
      Which version of Mesa?<br>
<br>
      I can&#39;t find any occurrence of &quot;Multi-LOD&quot; or &quot;giving \
up&quot; in the<br>  current Mesa code base.<br>
