Tearing/Corruption occurs with non standard tab sizes on xterm about cli-visualizer

[dpayne]

Sorry for the late response here. I am unable to reproduce the issue. I tried with both urxvt and regular xterm. Is it possible this is a really old or really low power machine? My hunch is that the the computer isn't powerful enough to clear the screen before the next redraw. It is pretty odd though that tabs size would make a performance difference.

I don't think my machine is low powered, it can handle cli-vsualizer at 60fps normally. This bug happens for me even when I set the fps as low as 10, so I don't think it's performance related (and I see this even when the terminal is very small). I'm not sure what could be causing it, maybe it's a weird issue with my specific version of ncurses, let me know if you have any other ideas.. 😢

Which version of ncurses are you using, you should be able to get it with cat /usr/include/ncurses.h| grep VERSION or with your package manager.

Here is the output of the command:

#define NCURSES_VERSION_MAJOR 6
#define NCURSES_VERSION_MINOR 0
#define NCURSES_VERSION_PATCH 20150808
#undef  NCURSES_VERSION
#define NCURSES_VERSION "6.0"
#define NCURSES_MOUSE_VERSION 2
#  define NCURSES_EVENT_VERSION	1
#define curses_version() NCURSES_VERSION
#if NCURSES_MOUSE_VERSION > 1
#if NCURSES_MOUSE_VERSION > 1

According to my package manager I'm using ncurses 6.0-r1

This is very odd, I cannot reproduce it at all. My only suggestion would be to uninstall ncurses then try re-installing from the latest source from here http://invisible-mirror.net/archives/ncurses/current/. Your ncurses version isn't that old so I'd be a little surprised if that fixed it but it might be worth a shot.

Also are you running this remotely or through a screen emulator?

[jgkamat]

I'm not running remotely, it's all on the local machine. I'll try out the ncurses thing in a couple of weeks, I don't want to mess around too much with my system right now. I'll try it out and let you know what I find! 😄

[jgkamat]

@dpayne I upgraded my ncurses version and that seems to have fixed all my problems. Since I can't reproduce anymore, closing.
