            <title>[MCPE-22739] Sending a chunk package in the same position of a previous chunk causes ghosting issues</title>
                <link>https://bugs.mojang.com/browse/MCPE-22739</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;If you send a chunk package with the same position of a chunk package you have previously sent the new chunk does not always correctly override the old one. Often the highlighting of blocks can be seen for the blocks of the new chunk, but visually the old chunk is rendered. &lt;/p&gt;

&lt;p&gt;In the screenshot included it can be seen that I am highlighting a seemingly invisible block (from the new chunk) yet the old chunk with air is rendering.&lt;/p&gt;

&lt;p&gt;This bug is a major issue for servers as there is few ways to get around it (off-setting of the chunks means that the problem is only hidden, and ghosting issues can still occur). &lt;/p&gt;

&lt;p&gt;It should be noted that breaking a block in a location where this visual error is present begins to render the new chunk, but still leads to other problems.&lt;/p&gt;

&lt;p&gt;Devices Tested Upon: Google Nexus 5, Samsung Galaxy S7 Edge&lt;/p&gt;</description>

                            <comment id="389817" author="onethousand" created="Tue, 20 Jun 2017 20:46:05 +0200"  >&lt;p&gt;Still reproducible as of 1.1.1.1, only slightly better. The old chunks no longer display (well, they load out slowly) but the new chunks still don&apos;t visually render.&lt;/p&gt;</comment>
                            <comment id="389302" author="depressed-pho" created="Mon, 19 Jun 2017 07:59:52 +0200"  >&lt;p&gt;That ghosting symptoms also occur on single-player now, possibly because the game has a server internally for single-player game.&lt;/p&gt;</comment>
                            <comment id="389283" author="ctrlaltcuteness" created="Mon, 19 Jun 2017 02:13:06 +0200"  >&lt;p&gt;This also happens on Realms. I&apos;ve had to open the door manually just to get inside when it looks open. This is a lot rarer when playing off your own device alone, but still possible, just very difficult to encounter on normal survival.&lt;/p&gt;</comment>

                            <comment id="389244" author="onethousand" created="Sun, 18 Jun 2017 19:52:42 +0200"  >&lt;p&gt;There is no way to unload a chunk manually, I am indeed sending the correct package, this bug has been reported and confirmed with Mojang staff privately yet there is no fix yet.&lt;/p&gt;</comment>
                            <comment id="389239" author="pokechu22" created="Sun, 18 Jun 2017 19:26:10 +0200"  >&lt;p&gt;I don&apos;t know the PE protocol (I&apos;m used to the Java one), but on the PC protocol, you are required to either unload the chunk and load it again (sending 2 full chunk data packets breaks things), or to disable a Boolean field in the chunk data packet (which tells it that the packet is only changing certain sections of the chunk, not a full one itself).  Are you &lt;em&gt;sure&lt;/em&gt; you&apos;re sending the packets right?  And are you sure this classifies as a vanilla bug, and not something that&apos;s &lt;em&gt;only&lt;/em&gt; exposed through custom servers (which are not supported on this tracker)?&lt;/p&gt;</comment>

&lt;p&gt;Issue occurs on my PocketMine server, using version 1.1.0.55&lt;br/&gt;
Play.atpe.co : 19132&lt;/p&gt;
