I'm just playing around with a new clean frugal of Fossapup64, first problem noticed is choosing from menu Desktop -- JWMDesk -GTK Theme - Icon Theme - Rox and re-starting graphic manager doesn't work, the original theme remains.
Also I don't like any of the (only) three GTK (widget) low contrast themes colors -- hard to read on this computer. But the color tab doesn't allow me to change colors -- it's all grayed out. Is that intentional?
