TreeView cell borders are too faint
As the title says. I noticed lately that if I have a line of code in gtkmm like this, it works fine for the dark Adwaita variant
however the gridlines lines no longer show with the light variant, this happens both in fedora 31 and latest Manjaro, but it used to be fine in Fedora 30.
Can it be fixed or was it done by design ? (If so, to me it looks poorly)
I would add that if I wanted that option in code I would simply say
but seeing the options are there, they should work to give the developer that choice .. IMHO
I can provide screenshots if need be, hopefully I'v provided enough info, but ask away ...
