            <title>[MCPE-15268] Blocks momentarily become invisible when moved by pistons</title>
                <link>https://bugs.mojang.com/browse/MCPE-15268</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;When I switching the piston or sticky piston on and off with any block on them, blocks are blinking (visible-invisible-visible).&lt;/p&gt;

                            <comment id="468334" author="mindblown" created="Sat, 7 Jul 2018 05:48:53 +0200"  >&lt;p&gt;&lt;del&gt;No, they are noticably faster in 1.2.6 but they did slightly increase after 16.0. But its not that different though.&lt;/del&gt;&#160;&lt;/p&gt;

&lt;p&gt;Never mind, I must&apos;ve forgotten. It was 1.2.6&lt;/p&gt;</comment>
                            <comment id="468324" author="henry markle" created="Sat, 7 Jul 2018 04:43:54 +0200"  >&lt;p&gt;No, I don&apos;t think so, the pistons became faster after 1.2.6&lt;/p&gt;</comment>
                            <comment id="468318" author="mindblown" created="Sat, 7 Jul 2018 04:22:19 +0200"  >&lt;p&gt;I think that is because they made pistons faster after 0.16.0 which made it harder for devices to render the piston extension and retraction along with blocks.&lt;/p&gt;</comment>
                            <comment id="468310" author="henry markle" created="Sat, 7 Jul 2018 03:04:48 +0200"  >&lt;p&gt;It&#160;reminds me of the 0.16 release when this bug was fixed the same way, but slightly better, then it came back in the 1.0-second beta release.&lt;/p&gt;

&lt;p&gt;The interesting thing is the fix wasn&apos;t written in the changelog site.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Edit: Maybe they didn&apos;t really mean to fix it at that time, maybe it was accidentally fixed by changing other mechanics, and it came back for the same reason. I don&apos;t really know.&lt;/p&gt;</comment>
                            <comment id="468309" author="mindblown" created="Sat, 7 Jul 2018 02:33:37 +0200"  >&lt;p&gt;Seems to depend on the device. I tested this on W10 and PE. In W10 it was fine even with about 6 pistons moving at the same time but in PE it was like how you described it, it would not render the blocks properly.&lt;/p&gt;</comment>
                            <comment id="468261" author="henry markle" created="Fri, 6 Jul 2018 21:17:02 +0200"  >&lt;p&gt;Jeffrey, I&apos;ve tested the latest beta (1.6.0.5) myself, and I do agree with you.&lt;/p&gt;

&lt;p&gt;The blocks no longer momentarily become invisible when being moved by a piston/sticky piston, but it comes with a new kinda problem.&lt;/p&gt;

&lt;p&gt;Here&apos;s the full details:&lt;/p&gt;

&lt;p&gt;First thing I&apos;m using Android phone to test the beta.&lt;/p&gt;

&lt;p&gt;There&apos;s almost no problem when using one piston/sticky to move one block, but when it comes into larger scales like 2*2 piston door, you can barely see the blocks moving, just disappearing and appearing from point (A) to point (B).&lt;/p&gt;

&lt;p&gt;It becomes even worse when you cover the piston door and the hole redstone with it.&lt;/p&gt;

&lt;p&gt;Probably it&apos;s something to do with the performance, and it renders better with higher-end devices.&lt;/p&gt;

&lt;p&gt;Whatever the way the devs used to fix the bug it&apos;s definitely better.&lt;/p&gt;

&lt;p&gt;Thank you.&lt;/p&gt;</comment>

                            <comment id="467992" author="henry markle" created="Fri, 6 Jul 2018 00:08:44 +0200"  >&lt;p&gt;Was this bug fixed in the 1.5 or 1.6 beta?&lt;/p&gt;

&lt;p&gt;Edit: It&apos;s really unsatisfing to watch piston machines work with this bug, not like in Java&lt;/p&gt;</comment>
                            <comment id="456110" author="mindblown" created="Sun, 27 May 2018 18:59:22 +0200"  >&lt;p&gt;Sorry, I misunderstood. You meant that they dont appear for a while, right? I thought it was the short flash of the block when they are moved. My bad.&lt;/p&gt;</comment>
                            <comment id="456072" author="yolo_37" created="Sun, 27 May 2018 16:03:15 +0200"  >&lt;p&gt;A bug actually is&#160;a feature not wanted by developers. So I think it could completely be considered as bug.&#160;&lt;/p&gt;</comment>
                            <comment id="456031" author="mindblown" created="Sun, 27 May 2018 11:15:05 +0200"  >&lt;p&gt;I wouldn&apos;t really consider this a bug. There is just a delay when moving blocks, the game has to unload a block then load it in another location. If you ask me this poses no issue nor problems whatsoever. Even java has this split-second delay.&lt;/p&gt;</comment>
                            <comment id="408091" author="nikokun" created="Sat, 23 Sep 2017 06:31:48 +0200"  >&lt;p&gt;I&apos;m still seeing this bug even now after the 1.2 update.. Hope it gets fixed eventually, it makes piston doors and other piston-moving contraptions look sloppy, graphically/immersion wise.&lt;br/&gt;
Edit: On PC as well.&lt;/p&gt;</comment>

That blinking block actually loses its solidness for a short time when the block is being pushed upwards.
