User & Groups settings text top down and reversed When I go to settings -> user &amp; groups then, all text and components in the container are reversed like the picture and clicking a component will not response anything.

It is shared mac mini with OS X Yosemite 10.10.2, I connected it with VNC client.

Logout and login do not help.

Can somebody help me how to fix it?



Edit

After reboot the mac, it is corrected.
I don't know why it happened but rebooting the mac solved this issue. I filed this issue to Apple.
