Created attachment 685348 [details] mc Description of problem: Running mc under screen and moving cursor will show some characters as black. This is very random, unable to tell exactly when happens. Version-Release number of selected component (if applicable): initscripts-9.42.1-1.fc18.x86_64 ncurses-5.9-7.20121017.fc18.x86_64 mc-4.8.6-2.fc18.x86_64 roxterm-2.2.2-3.fc18.x86_64 How reproducible: random Steps to Reproduce: 1. screen 2. mc /lib /bin 3. move cursor down/up, scroll in large directory, move over screen Actual results: see screenshot Additional info: Looks like it has something with TERMCAP. Clearing TERMCAP will fix this bug. I am not sure, which component is responsible for this.
I think the problem will be in screen, mc or slang. ncurses shouldn't be involved here. This is going to be hard to debug. I think it might help if you run both mc and screen in the script utility and tried to capture the output which triggers the problem. The typescripts could be used to narrow down the problem. Reassigning to screen.
To reproduce this, you need an 256color capable terminal, for example xterm, roxterm or konsole. rxvt are not yet functional in Fedora 18. Also disabling 256 colors in TERMCAP fixes my problems, so looks like this is an incompatibility of screen with 256 colors.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.

In F16 it worked fine. Thus, seems as regression for me.
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Looks like this is already fixed in Fedora 20. Don't know, when it was fixed. Leaving open until automatic close.
(In reply to Jan ONDREJ from comment #6) > Looks like this is already fixed in Fedora 20. Don't know, when it was fixed. > Leaving open until automatic close. My mistake. Still present in Fedora 20. As a workaround I use this in .bashrc: # disable 256 color term export TERMCAP=$(echo "$TERMCAP" | sed -e 's/Co#256/Co#8/g')

Looks like this bug will never be fixed. And workaround is to switch from screen to tmux, which has no similar problems and many advantages. Tmux can be configured to emulate screen keyboard syntax.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
