I am running Mathematica on Linux (Raspbian to be exact), and it seems I am missing some Mathematica fonts:
Is there a way to fix this?
Just to save visitors from having to click through to other sites, the issue here is that the default color depth for Raspbian (the Raspberry Pi flavor of Linux) is 16 bit, and Mathematica expects 24 bit or higher. In
/boot/config.txt add the lines
# To make 3D plots in Mathematica look nicer framebuffer_depth=32 framebuffer_ignore_alpha=1
The last line does not appear to be absolutely necessary; I cannot easily notice a difference in performance.
For reference, the original issue was identified on the WC site and details for changing the color depth are found in a variety of places such as here. The question about performance was mentioned in the github issue tracking back a few years, and may no longer be relevant. (At least, it isn't on my v2 or v3 units.)
