Ubuntu 17.10 final with all updates - bug is not fixed.

Ubuntu MATE 17.10 is affected too. Scilab is unusable with default Ambiant-MATE theme.

It looks like Scilab is hard-coding black (and white) fonts in a couple of places. That may be a problem confined to the Scilab source code.

What does it look like with cosmic's Yaru theme?

Norbert (nrbrtx) wrote :

Tested Yaru theme on Cosmic - it does not change anything. Still have very low contrast.

Daniel van Vugt (vanvugt) wrote :

Thanks. That eliminates the possibility of the bug being in 'ubuntu-themes' since Yaru is outside of that. So this looks like a bug localised to Scilab.

Changed in ubuntu-themes (Ubuntu):
