Graphical glitches on FreeBSD

Fontforge version: fontforge 01:43 UTC 14-Mar-2017 libfontforge 20170314 (Built from github source) OS version: FreeBSD 10.3-RELEASE Whenever I edit a glyph, the lines are a lot thicker than I experienced within the macOS version, and the right border is missing (an example of the usual behavior would be the screenshot on your main page, and it's easier to see when the image is at actual-size, rather than the smaller size shown in the issue view): EDIT: This was because my outline thickness was set to 3, not 1. The other problems went away when I set the thickness to 1, but were there on 3

Also, I have to turn off the guide layer or else the guides are shown, but not the glyph (screenshot taken with the same settings as the previous screenshot, except that guides were turned on):

In addition, the lines do not stay the same width on the screen when I zoom in, but instead scale with the zoom, as shown in this screenshot of the same glyph after zooming in:

Also, when I run it from the command line, it gives this output:
