[screen-devel] Bug in rendering terminal application

[Maarten van Malland]

I think I've encountered a bug in the master branch with a specific
terminal application: https://github.com/0xbsec/terminal2048 This
application is working fine in several other terminals (termite, st,
terminator) as well as within tmux, but for some reason the fonts are
not rendered correctly within screen v5. In screen v4 it's not working
at all, so my suspicion is that this application is using truecolor
and screen v5 is having some issue with it. Any idea what might be
going on here?
