I've been testing this on 6.2. I notice one problem which exists
also for emacs-25 and I can reproduce it for all the graphical
flavors.
The scenario I can reproduce is related to using org-capture. On
any other platform, or even on OpenBSD without X, after selecting
capture template a dedicated buffer appears in which I can edit
the template. On OpenBSD however, under X this buffer does only
appear after generating additional input event, like moving a
mouse. There's no such problem if I select capture template using
soft-keyboard - XVkbd.
Also it is very likely that after selecting the capture template
*emacs will hang in kind of an infinite loop* maxing out CPU
usage.
The command I used to build the port:
cd /usr/ports/editors/emacs
doas sh -c 'export FLAVOR=athena; export DEBUG="-g -O0 -DTRACE_SELECTION";
make clean repackage reinstall'
The stacktrace from the moment it hangs:
