LyX becomes unresponsive to mouse

Yesterday I started some documentation work using my favorite LyX cygwin

After about 5 minutes, the LyX window and frame became completely
unresponsive to mouse interaction. I could resize the window but the
contents did not resize/rearrange to fit the change in window shape.
Doing "kill -9 PID-of-lyx" had no effect but if I killed the PPID-of-lyx
then the lyx window would close.
I tried running LyX with "strace lyx" which was slow on starting from
all the terminal output and then the window opened but the expected
contents were never displayed. It appears that the "hang" happened
before the strace lyx could complete its initialization.
Again, "kill -9 PID-of-lyx" had no effect but it worked if I killed the
PPID-of-lyx (i.e. strace and not bash this time).
I tried uninstalling and reinstalling the previous cygwin release
version and even the latest cygports version. All showed the same problem.
It may be useful that I had not had this problem previously with lyx on
windows 10 with cygwin. I don't know those version numbers but it was
before the move to Qt5 which I saw some discussion regarding LyX.
Has anyone seen this problem and/or have an idea for a fix? It seems
not to be specific to the recent LyX version number but I am not able to
try earlier than the 22.214.171.124-2 cygwin release.
At the moment, I am stuck without LyX under cygwin. I plan to try the
native LyX for windows to see if I can get LyX running for the near term.
