+<h3>catia-04</h3>
+
+<p>
+One of the catia tests calls wglGetProcAddress() to get some
+GL_EXT_direct_state_access functions (such as glBindMultiTextureEXT) and some
+GL_NV_half_float functions (such as glMultiTexCoord3hNV).
+If the extension/function is not supported, wglGetProcAddress() can return NULL.
+Unfortunately, Viewperf doesn't check for null pointers and crashes when it
+later tries to use the pointer.
+</p>
+
+<p>
+Another catia test uses OpenGL 3.1's primitive restart feature.
+But when Viewperf creates an OpenGL context, it doesn't request version 3.1
+If the driver returns version 3.0 or earlier all the calls related to primitive
+restart generate an OpenGL error.
+Some of the rendering is then incorrect.
+</p>
+
+
+<h3>energy-01</h3>
+
+<p>
+This test creates a 3D luminance texture of size 1K x 1K x 1K.
+If the OpenGL driver/device doesn't support a texture of this size
+the glTexImage3D() call will fail with GL_INVALID_VALUE or GL_OUT_OF_MEMORY
+and all that's rendered is plain white polygons.
+Ideally, the test would use a proxy texture to determine the max 3D
+texture size.  But it does not do that.
+</p>
+
+<h3>maya-04</h3>
+
+<p>
+This test generates many GL_INVALID_OPERATION errors in its calls to
+glUniform().
+Causes include:
+<ul>
+<li> Trying to set float uniforms with glUniformi()
+<li> Trying to set float uniforms with glUniform3f()
+<li> Trying to set matrix uniforms with glUniform() instead of glUniformMatrix().
+</ul>
+<p>
+Apparently, the indexes returned by glGetUniformLocation() were hard-coded
+into the application trace when it was created.
+Since different implementations of glGetUniformLocation() may return different
+values for any given uniform name, subsequent calls to glUniform() will be
+invalid since they refer to the wrong uniform variables.
+This causes many OpenGL errors and leads to incorrect rendering.
+</p>
+
+<h3>medical-01</h3>
+
+<p>
+This test uses a single GLSL fragment shader which contains a GLSL 1.20
+array initializer statement, but it neglects to specify
+<code>#version 120</code> at the top of the shader code.
+So, the shader does not compile and all that's rendered is plain white polygons.
+</p>
+
+<h3>showcase-01</h3>
+
+<p>
+This is actually a DX11 test based on Autodesk's Showcase product.
+As such, it won't run with Mesa.
