Кнопки заголовка слишком велики в Chrome

У меня была такая же проблема при установке фляжки на Ubuntu 14.04

$ sudo pip install flask 
Requirement already satisfied (use --upgrade to upgrade): flask in /usr/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): Werkzeug>=0.7 in /usr/lib/python2.7/dist-packages (from flask)
Requirement already satisfied (use --upgrade to upgrade): Jinja2>=2.4 in /usr/lib/python2.7/dist-packages (from flask)
Requirement already satisfied (use --upgrade to upgrade): itsdangerous>=0.21 in /usr/lib/python2.7/dist-packages (from flask)
Requirement already satisfied (use --upgrade to upgrade): markupsafe in /usr/lib/python2.7/dist-packages (from Jinja2>=2.4->flask)

. Решил ее, выпустив эту команду:

sudo pip install --upgrade flask.

Это устранит любые проблемы с флягой и установит это правильно.
