Hello list, using grc / gnuradio on Ubuntu (19.10 and 20.04) gives unreadable value entries in the variable editor or in the parameter editor if the parameter type is raw. In such a case the background colur of the value entry is black and the text colour is black, too. See attached screenshot.
Trying the same on a gentoo box everythings works fine. So I suppose, it's first a problem of the linux distro, not of gnuradio. But I could not find out wherefrom grc takes the settings of the value entry in the variable / parameter editor. Any hints would be appreciated -- Volker
