The same is true after additionally applying the patch 0001-try-no-grabs-in-function-execution.patch that you supplied in an earlier posting. I checked it for both, Player and Workstation, with equal result. Maybe you can post a patch of your experimental version of sources against the officially released ones in https://github.com/fvwmorg/fvwm/releases/download/2.6.7/fvwm-2.6.7.tar.gz so we have assuredly identical copies?
