Recently (September 2015), when I’m in Dashboard, the left side menu does odd things when you scroll. Specifically, text links will move around and stack on top of each other. Not really a big deal, but pretty annoying when you’re trying to write posts, or edit pages, right?
It looks like it’s a known issue with Google Chrome v45. Luckily, there’s an easy fix.
- Go to chrome://flags/#disable-slimming-paint (Just copy/paste it into Chrome’s address bar.)
- Enable the “Disable slimming paint” option. (Should be the top entry on the page that comes up. See image below.)
- Enable the “Enable slimming paint” option. (Should be the second entry on the page that comes up. See image below.)
- Relaunch Chrome. (Using the big button at the bottom of the page.)
Once you relaunch Chrome, it should look right again.
Hope this helps. I actually found the fix here… https://wordpress.org/support/topic/admin-sidebar-is-all-messed-up
It looks like there is also a plugin on Github that adds some CSS to WordPress to fix the problem, but I have about 50 WordPress websites to manage, so fixing Chrome sounded like a much better idea.
