I'm unable to reproduce this on a clean install of Trusty with all updates.

[Sebastien Bacher (seb128)]

Thanks, could you try if that's still an issue in the current version? It works fine here...
Is that also specific to firefox?

[Alberto Salvia Novella (es20490446e)]

Yes, it's still here. And doesn't happen in the Files application, neither in Thunderbird.

[madbiologist (me-again)]

I can't reproduce this in Firefox on a clean install of Vivid with updates either.

[madbiologist (me-again)]

I have menus set to show in the window's title bar. Do you?

@ madbiologist

Yes, I have too. The default configuration.

Moreover I reinstalled Ubuntu, installed all the applications I had, and the bug is still there. Moreover I can reproduce it in a very different computer with the same set of applications.

So please have a look at the attached video and try to reproduce the bug exactly as shown. Thanks 😉
