Capturing the flag can change cecho/csay enviroment

When you csay/cecho text, it's always caps on. But try capturing the flag and its letters won't be capped on and fads out instead of disappearing immediately. I think csay/cecho now follows the CTF screen text system and won't revert unless you reset the game

The command CECHOFLAGS is meant to set the video flags for CECHO: https://wiki.srb2.org/wiki/Console/Commands#cechoflags_.3Cinteger.3E

In some sense, you're expected to set the flags before any use of CECHO for consistent behavior, though whether or not this is desirable is another story entirely.
