Installing tex fonts messes up plots

[JorisGoosen]

If one is working on Ubuntu 20.04 and one installs certain tex fonts, for instance "texmaker" and its related pkgs. ggplot2 no longer seems to render plots properly.

library(GGally)
ggpairs(mtcars[, c('mpg', 'cyl')])

Results in:

If I remove all tex related stuff from Ubuntu I get this:

Im guessing the fonts shouldn't stop working after installing tex but maybe im missing something.

This mostly came up for us at JASP through this issue: jasp-stats/jasp-issues#780 and there we can work around the problem by uninstalling "tex-gyre" but I don't understand why ggplot starts using these fonts, or getting messed up by it.

This an issue with the png device and how it interprets mono fonts. There is nothing we can do from the ggplot2 side, but I know the issue has been raised. You can use the devices from ragg instead to avoid it, though it doesn't provide a windowed device, only file devices

Ah thank you for the response!

Ok, I guess we will try that then. Luckily we don't need windowed devices.
