Generic cube icon instead of the icon of the app in the qube

Xterm has some issue with icons, no idea why:

Question on xterm*iconHint in VMs

I am trying to find the exact reason Xterm instances of VMs do not show their Icon and revert to the Qube icon instead. To my understanding, it is possible to select the desired .xpm icon by using something like: xterm -xrm "xterm*iconHint: /usr/share/pixmaps/xterm-color_48x48" Or any of the other .xpm icon variants rather than xterm-color_48x48.xpm The above command works well in dom0. Not in VMs. Is this some issue with qubes-gui-daemon?
