Noticeable delay in copy paste

[ravi r]

After two years of using an older version of cygwin, a week ago, I
       CYGWIN_NT-10.0-19045 version 3.4.7-1.x86_64
(runneradmin@fv-az416-306) (gcc version 11.4.0 (GCC) ) 2023-06-16
14:04 UTC
upgraded cygwin to the latest version.

Ever since the upgrade, I see noticeable delay in copy pasting text
from Chrome browser to 'vim' editor session
running inside a xterm under fvwm.

Need assistance on additional commands that I could  run to find the
cause of this issue.
