Thanks, unfortunately this looks like a genuine heisenbug and my
earlier reports should be deemed unreliable. I do have builds which
"don't work" but I'm am now unable to produce *new* builds which
"don't work", (say with adding printf debugging or resetting)
AFAICT both XtGrabPointer and XtGrabKeyboard return Success in all
cases (both "works" and "doesn't work" builds) - keyboard and pointer
are both grabbed as expected - from gdb dprintfs, disassembly seems
identical.
The only significant thing I can report (I have libinput
enable-tab=true) on a "doesn't work" build is that if i quickly make
two single taps on the help button on the toolbar, on the touchpad,
then the pop-up-menu "works". (the effect seems to be an event
between the activation of the menu and the display of the menu - F10
doesn't work as usual). There hasn't been any progress Sorry
