            <title>[MC-3503] block surfaces are generated under stairs and steps</title>
                <link>https://bugs.mojang.com/browse/MC-3503</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Block surfaces are generated under ohterblocks in all Version&lt;/p&gt;

&lt;p&gt;1. stairs&lt;br/&gt;
2. steps&lt;br/&gt;
3. snow&lt;br/&gt;
4. redstone repeater&lt;br/&gt;
...&lt;/p&gt;

&lt;p&gt;I think it is consumed by more efficient.&lt;br/&gt;
if they block surfaces are rendered unnecessary&lt;/p&gt;</description>

If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/p&gt;</comment>
                            <comment id="35975" author="quimoth" created="Sat, 12 Jan 2013 13:12:39 +0100"  >&lt;p&gt;minecraft just doesnt see the difference between blocks that are visible when placed next to stairs/slabs and blocks that are not visible. if a block is partly transparent then minecraft will render all 6 blocks around it. could be considered a bug but i think that testing which blocks should and which blocks shouldnt be rendered wont make the game much faster. atleast for stairs that will be the cause if you would ask me. slabs are easier because there is only 1 extra block that doesnt have to be rendered and that block can be only below or under the slab.&lt;/p&gt;</comment>

If Minecraft only rendered &quot;visible&quot; blocks as per your suggestion, a piece of glass on the ground would have blue instead of transparency.&lt;/p&gt;</comment>

So it would still save power if it would change?&lt;/p&gt;</comment>

Is this causing your problem?&lt;/p&gt;</comment>
