Created attachment 527672 [details] Screenshot of nmon showing rendering problems Since some system updates I see strange rendering problems in nmon. Doesn't matter which version. See screenshot attached. Happens in KDE console, lxterminal. Classic x11-terms/xterm and linux text console seem not to be affected.
In Fedora they were applying this patch to fix some "rendering issues with ncurses apps" with konsole-17.12* https://src.fedoraproject.org/rpms/konsole5/raw/43cde26ed8a4e3162ed87fa0d3b48b1eb70a5220/f/konsole_REP.patch Maybe you could give it a try
I have the same issue but with xfce4-terminal; all other ncurses-based apps work (alpine, htop..) except nmon, and the problem is definitely the recent ncurses update to 6.1. Everything was fine with 6.0. Since 6.0 is now gone I was forced to update as well and started investigating. What I found was that while xfce4-terminal sets TERM to "xterm" by default, setting TERM to something else in the shell ("konsole" or "xterm-color" worked for me) seems to fix the problem and nmon immediately renders properly again. I have no idea whether this is a problem with the terminal emulator, ncurses or the application itself. So tl;dr: try to set TERM=xterm-color in your profile.
I haven't been able to replicate the issue with other VTE-based terminal emulators. Did somebody try if the patch works and if it breaks other stuff?
tazinblack, please attach the emerge info and the build log, as well as the DE/WM you're using. I can't reproduce the issue with Konsole in i3 on X.

Are you using 6.1-r2 ncurses and is nmon built against it? If not please rebuild and test again.

Yes I use that version and to make sure nmon is build against it I just rebuilt it. But that does not change the behavior. A functional workaround is to change $TERM from xterm-256color to xterm-color before starting nmon with 'export TERM="xterm-color"'
Created attachment 537266 [details] build log of nmon
if you give me detailed instructions how to apply the patch mentioned above I'm going to give it a try
Is this still an issue...?
