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>

&lt;p&gt;I updated driver and bugs disappeared, however it can occur again&lt;/p&gt;</comment>
                            <comment id="51550" author="kumasasa" created="Sun, 10 Mar 2013 10:54:19 +0100"  >&lt;p&gt;You mean Options -&amp;gt; Video Settings -&amp;gt; Performance ?&lt;br/&gt;
Which setting (Max FPS / Balanced / Power Saver) shows what behaviour ?&lt;/p&gt;

&lt;p&gt;You might try to update your graphics drivers, you have version 11762 (unknown which Catalyst version), current is 12002 (Catalyst 13.1 : &lt;a href=&quot;http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx&lt;/a&gt; )&lt;/p&gt;</comment>
                            <comment id="51540" author="zanozus" created="Sun, 10 Mar 2013 10:32:04 +0100"  >&lt;p&gt;Oh, NO ! I have flickering and redstone anomaly in new world again !&lt;br/&gt;
They appeared simultaneously. I think it caused by sudden reboot of my computer due to loss of power.&lt;br/&gt;
And it depends on &quot;perfomance&quot; option of minecraft.&lt;/p&gt;</comment>
                            <comment id="51148" author="zanozus" created="Fri, 8 Mar 2013 22:37:14 +0100"  >&lt;p&gt;No, flickering doesn&apos;t depend on CPU frequency or tool.&lt;/p&gt;

&lt;p&gt;I spent some time to invent new algorithm for elevator and I&apos;m sorry that I waste time due to bugs. But in new world all works perfectly and I haven&apos;t got any troubles.&lt;/p&gt;</comment>
                            <comment id="51134" author="kumasasa" created="Fri, 8 Mar 2013 22:15:13 +0100"  >&lt;p&gt;Does the flickering only occur if you switch processor frequency ?&lt;br/&gt;
With other words, if you start Minecraft without any CPU freq changing tool running ?&lt;/p&gt;

&lt;p&gt;Regarding the changing repeater delay: &lt;br/&gt;
That doesn&apos;t look like a minecraft bug (thus invalid here), because Minecraft / Java / LWJGL will calculate idle loops when starting and does take in account that the user will deliberately change CPU frequency. &lt;br/&gt;
BTW: Why did you do that ? Just as a proof of concept ?&lt;/p&gt;</comment>
                            <comment id="51131" author="kumasasa" created="Fri, 8 Mar 2013 22:10:17 +0100"  >&lt;p&gt;No flickering.&lt;/p&gt;</comment>
                            <comment id="51122" author="zanozus" created="Fri, 8 Mar 2013 21:50:20 +0100"  >&lt;p&gt;I can&apos;t reproduce this bug in new world. Where is no flickering or redstone anomalies.&lt;br/&gt;
I added my save.&lt;/p&gt;</comment>
                            <comment id="51119" author="zanozus" created="Fri, 8 Mar 2013 21:45:23 +0100"  >&lt;p&gt;I use Phenom 2 x4 processor and toogle frequency by &quot;PhenomMsrTweaker&quot; manually or automatically.&lt;/p&gt;</comment>
                            <comment id="51114" author="zanozus" created="Fri, 8 Mar 2013 21:42:16 +0100"  >&lt;p&gt;Can it be connected with RamDisk or SSD disk ? I have Minecraft installed on RamDisk to accelerate it.&lt;/p&gt;</comment>
                            <comment id="51109" author="kumasasa" created="Fri, 8 Mar 2013 21:40:02 +0100"  >&lt;p&gt;Dependancy between the repeater delay and the flickering items ?&lt;/p&gt;

&lt;p&gt;Can you attach a zip of your world here (or create a new world which shows the issue) ?&lt;br/&gt;
Maybe people of &lt;a href=&quot;https://bugs.mojang.com/browse/MC-11033&quot; title=&quot;Item count / numbers randomly flickering in item bar, inventory, workbench&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-11033&quot;&gt;&lt;del&gt;MC-11033&lt;/del&gt;&lt;/a&gt; may test if there is a coincidence between the two issues.&lt;/p&gt;

&lt;p&gt;But another question: Why does your CPU change frequency ? What CPU do you have (attach a screenshot of CPUID &lt;a href=&quot;http://www.cpuid.com/softwares/cpu-z.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://www.cpuid.com/softwares/cpu-z.html&lt;/a&gt; ) ?&lt;/p&gt;</comment>
                            <comment id="51103" author="zanozus" created="Fri, 8 Mar 2013 21:23:16 +0100"  >&lt;p&gt;Better quality (13 mbytes):&lt;br/&gt;
&lt;a href=&quot;https://www.dropbox.com/s/mdhqyskw30h92yw/clip0003.avi&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://www.dropbox.com/s/mdhqyskw30h92yw/clip0003.avi&lt;/a&gt;&lt;br/&gt;
Yes, there is flickering item icon too&lt;/p&gt;</comment>
                            <comment id="51090" author="kumasasa" created="Fri, 8 Mar 2013 21:07:59 +0100"  >&lt;p&gt;I didn&apos;t expect that the issue would vanish with the update of Java, that was just a general hint.&lt;br/&gt;
But as I could see in the clip that you have the flickering hotbar numbers as described in &lt;a href=&quot;https://bugs.mojang.com/browse/MC-11033&quot; title=&quot;Item count / numbers randomly flickering in item bar, inventory, workbench&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-11033&quot;&gt;&lt;del&gt;MC-11033&lt;/del&gt;&lt;/a&gt; ?&lt;/p&gt;</comment>
                            <comment id="51086" author="zanozus" created="Fri, 8 Mar 2013 21:00:12 +0100"  >&lt;p&gt;I updated Java, but nothing changed. I attached a video, it&apos;s very bad quality.&lt;/p&gt;</comment>
                            <comment id="51069" author="kumasasa" created="Fri, 8 Mar 2013 20:14:31 +0100"  >&lt;p&gt;Nothing to see in the crash report, except that your Java is outdated. Current version is 1.7 Update 17.&lt;/p&gt;</comment>
                            <comment id="50787" author="kumasasa" created="Thu, 7 Mar 2013 20:26:24 +0100"  >&lt;p&gt;Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.&lt;/p&gt;</comment>
