    Go figure, shortly after publishing this post, the Chrome Development bumped up the priority of the bug and a fix is likely come out before version 47 https://code.google.com/p/chromium/issues/detail?id=509179

    Wow, I never noticed it until now. Yes, I can reproduce the issue with version 45.

    I thought my site was compromised somehow (corrupt files,etc…). One easy fix for me was to collapse the menu to icons, and then expand it again. Very annoying… .

    At least the Customizer is fine though !!!

    To disable this feature, visit chrome://flags/#disable-slimming-paint in Chrome and click the disable link.

    Note that this is slightly confusing here, because it’s bloody Chrome so of course it is.

    You actually have to “Enable” the “Disable slimming paint” option, and make sure that the other two “Enable” options are actually disabled, because they will override the Disable option.

    If you got a headache from reading that, you’re not alone.

    Just go by this picture of what it should look like instead:
    Cloudup qhfjldalkv4

    That’s how it needs to be. This will disable the problematic code in Chrome and allow the menus to render normally.

      Yeah, that made me laugh pretty hard!

    yet another win for automatic updates. I wish I could say that my browser is different (firefox), but it isn’t :(. Maybe time to seriously consider using IE.

    Thank you! I’ve been trying to figure out how to do this for a month now. I ended up rediscovering Firefox… Perfect fix. Seriously. Thank you.

    Hi, there is also an other fix which you can install on your clients’ sites and that’s a plugin at:
    https://github.com/raffjones/chrome-admin-menu-fix which has been provided by raffjones.

    I used it and it works.

    You should mention it in the article.

    I’m using 45.0.2454.85 m (64-bit). I don’t see a second phase to disable and setting the first two flags as instructed doesn’t fix the issue.

    Now if they could just fix the constant memory sucking and crashes that also came with 45.0.2454.85. I upgraded to this version today and Chrome uses up about 1,000,000k every 2 hours which crashes the whole browser. Have to now use Firefox only again.

    Looks like they moved fast; mine (on the beta channel) just updated to “46.0.2490.13 beta-m” and everything’s working again in the admin sidebar.

    Report

    • Samuel "Otto" Wood

      No, they have not made any fixes yet. Chrome 46.0.2490.13 beta-m (64-bit) definitely still has the problem, at least it does on Windows 10.

      The problem is slightly random in nature. You don’t see it every time. You do see it quite a lot of the time though, it’s very reproducible.

    I suspected Chrome, which often has partially baked additions crop up. So I checked Firefox, which works fine.

    Thanks for the additional confirmation. The true name of this might be Slimming Pain, then. :)

    If one doesn’t want tell all the people that have access to wp-admin to disable “slimming painting” this code added to functions.php could be a work around until an official fix is released:

    add_action('admin_enqueue_scripts', 'chrome_fix');
    function chrome_fix() {
    	if ( strpos( $_SERVER['HTTP_USER_AGENT'], 'Chrome' ) !== false )
    		wp_add_inline_style( 'wp-admin', '#adminmenu { transform: translateZ(0); }' );
    }

    This bug is indeed super annoying, but I have a question about your fix. If I disable slimming paint now, when Chrome releases the update will it return my slimming paint settings to normal? I prefer not to have any weird/obscure settings set to abnormal setting like this when it’s not necessary.

    Thanks for posting this article, I’ve just started using Word Press and this has been driving me nuts! Simple fix when you know how!

    One this I noticed was there was only One enable option to change (double checked with a CMD + F) but it seems to have worked anyway. Just wondering if there is any reason you know of that would mean I am missing one?

    Thanks for this! I noticed the menus, but on one of my sites I noticed that the pages were displaying incorrectly; elements were repeating and odd colors where interspersed. Once I implemented this fix, ALL of that went away and the site itself was displaying as intended.

    Note that the Chrome team has found and fixed the bug, and it will be in chrome canary tomorrow. However, it likely well not get pushed into chrome 45, but will be in chrome 46, in a few weeks.

    Chrome update: They fast tracked the bug fix. It’s currently scheduled to be released in Chrome 45 (branch 2454) and Chrome 46 (branch 2490) somewhere within 1 week. The fix is in Chrome Canary (47) right now.

    And there is still the issue that a different (red) background for a menu item in the top admin bar is not displayed in Chrome. It does in IE.
    This is used in the lj-maintenance mode plugin.

    Hi all! Hi Jeff! Thank you all for this post, the solution and the discussion. Yet…

    I’ve heard or read no one complain about Opera. The Browser. Yet, that’s the one I use, and the issue is exactly the same. I reckon I can wait till my face grows a 3ft beard till that be fixed, right? What do you reckon?

    Kindest regards from the Netherlands

    Part 2:
    After having dealt with this for weeks (I mean, it’s not the end of the world) I’ve found an ugly but easy quick fix, for anyone who still experiences this:

    when your mouse is hovering over the WP admin menu, try zooming in (CTRL-+) and zooming back to normal (CTRL-0) again. That appears to set it all back into place for that moment.

    Yes. A workaround. Ugly. Stupid even. But it works :)

    I began to use a WordPress theme called Customizr for a website two months ago but for reasons unknown my preferred browser Chrome (Version 47.0.2526.106 m) has crashed at least three times since then, which led to loss of hours of work. Ever since I switched to Firefox I have never experienced a single crash. A bit digging online turned up evidence that others have had or are having the same problem with Chrome.
