XQuartz under macOS Sierra repeatedly appears, disappears in Dock; app using it never starts

Under macOS Sierra (10.12.3), Xquartz 2.7.11 is not working with two apps that use it, namely, Rcmdr from within RStudio and the current Macports port of Inkscape (port inkscape @0.92.0_3+x11 together with inkscape-app @0.92_0).
For each, when I start the app, Rcmdr or Inkscape, the XQuartz icon repeatedly appears in the Dock and then quickly disappears; the app never actually opens.
Version: 2.7.11 (xserver-1.18.4)
