            <title>[MC-7934] Extreme lag and random killing of players</title>
                <link>https://bugs.mojang.com/browse/MC-7934</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;When I am playing on my server I notice extreme lag. This includes render lag too. I can&apos;t type commands, and it takes forever to load the world in front of me. But, after a while, it randomly kills me. And when I check chat, it says it tried to kill me several times.&lt;/p&gt;</description>

&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;OpenGL: Intel GMA 950 OpenGL Engine GL version 1.4 APPLE-1.6.36, Intel Inc
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;GMA 950 is on the lowest end of Minecraft capable graphics cards.&lt;/p&gt;

&lt;p&gt;Resolving this ticket since lag / graphics card issues are not a Minecraft bug.&lt;br/&gt;
