New comment by Goorzhel on void-packages repository https://github.com/void-linux/void-packages/pull/38816#issuecomment-1366182981 Comment: Well, damn. I downloaded the [latest FLTK snapshot](https://www.fltk.org/pub/fltk/snapshots/fltk-1.4.x-20221223-e7eac09c.tar.bz2) (fltk/fltk@e7eac09c), compiled the tests, and saw them display perfectly. Then [I downloaded the 1.3.8 release](https://www.fltk.org/pub/fltk/1.3.8/fltk-1.3.8-source.tar.gz) separately, compiled the tests there\*, and got that all-black UI again. It seems this is stuck until FLTK 1.4. \* `./configure && make -j8 && ./test/preferences`
