Comment (by raimue):

 I can confirm I have the same display problem now. I might not have had
 that on Yosemite when I initially wrote this port.

 I went with pyqt5, as although upstream sees pyqt4 as the stable variant,
 the bundled [https://github.com/spyder-ide/qtpy qtpy] will prefer pyqt5
 over pyqt4. The only way to change that without patching seems to be to
 export `QT_API=pyqt4` in the environment before running git-cola.

 Switching to `py35-pyqt4` with this method seems to resolve the issue.
 I'll work on a patch to switch to our qtpy port and make git-cola prefer
 the pyqt4 interface.
