Hi Antti, The behavior you describe has not changed for over a decade. That 'z' has always been window specific, affecting just a single window. It’s documented in the man page under 4c. Task-Area-Commands.
What has changed are the startup defaults in the absence of a previously saved rcfile. They now include colors unless top was built with ./configure —disable-modern-top. Unfortunately, not all aspects of saved rcfiles were honored. Please see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=762928 I think that’s the bug which has put your eyes at risk. A fix is on the way (but it only affects saved rcfiles). I’ll ask Craig to close this report.
