No issues when these programs run in proper cygwin terminal (mintty). I found two workarounds, but neither one is perfect. One is to set TERM=cygwin but less won't clear the screen on exit and home/end don't work (incidentally setting TERM=xterm like in minnty doesn't help at all). Another workaround is to switch windows console to legacy mode. Is there a better way to run these programs in windows console without starting mintty?

I cannot reproduce your problem.

Please provide
cygcheck -s -v -r
