patch for ncurses-5.5-26/RHEL5.3
This seems to be fixed in upstream patches 20070630 and 20070707: 20070707 + improve fix for refresh of window on top of multi-column characters, taking into account some split characters on left/right window boundaries. 20070630 + partial fix for refresh of window on top of multi-column characters which are partly overwritten (report by Sadrul H Chowdhury). I think that fixes are for different situation, the issue reported here occurred with both ncurses-5.4-15 and ncurses-5.5-26, I think which are latest version for RHEL4 and RHEL5. Would you please run a test with my attached codes ? I run the test and the patches seem to fix it. But I tried it only on RHEL5 (bug #519376), backporting for ncurses-5.4 will be a bit harder.

fix for refresh of window on top of multi-column characters
When will the issue be fixed on RHEL 4.x ? Can you just use my fixing patch for RHEL 4.7? I have tested it. This should work for RHEL 4.x. As RHEL-4.9 is last update for RHEL-4 and it is not suitable for new features and should address only security, performance and critical issues, I'm closing that bugzilla WONTFIX. Note - https://bugzilla.redhat.com/show_bug.cgi?id=519376 is opened bugzilla for RHEL-5. |
