I would guess based on the use of Homebrew you're on OSX and this might have something to do with retina display. I think there were some GLView issues in that case that were fixed after the most recent release (0.10.0). Could you try installing from the latest develop branch on GitHub and see if the issue persists: https://github.com/pyqtgraph/pyqtgraph/blob/develop/README.md#installation-methods
