It's generally frowned upon to have more than one H1 per document in HTML4. So let's put the text directly inside the header. This means we can drop the flex-based centering, which makes things a bit easier. We also need to change the padding to rem instead of em, because the em has now changed.

<h1>Debugging Tips</h1>
|
|
|
|
<p>
|
|
Normally Mesa (and OpenGL) records but does not notify the user of
|
|
errors. It is up to the application to call
|
|
<code>glGetError</code> to check for errors. Mesa supports an
|
|
environment variable, MESA_DEBUG, to help with debugging. If
|
|
MESA_DEBUG is defined, a message will be printed to stdout whenever
|
|
an error occurs.
|
|
</p>
|
|
|
|
<p>
|
|
More extensive error checking is done in DEBUG builds
|
|
(<code>--buildtype debug</code> for meson, <code>build=debug</code> for scons).
|
|
</p>
|
|
<p>
|
|
In your debugger you can set a breakpoint in _mesa_error() to trap Mesa
|
|
errors.

|
There is a display list printing/debugging facility. See the end of
|
|
src/dlist.c for details.
