Konsole v2.3.3 in KDE 4.3.4 on RHEL 6.5 64-bit. During command execution (under csh), stdout only prints and scrolls in some small portion of the lower screen instead of whole screen, resulting in corrupted display upon command completion. Moving elevator bar up a page, then pressing Enter or ^c results in correct display of last full screen. Using mouse scroll wheel also causes similar screen corruption. Appears to be intermittent. Prior versions of KDE worked ok. I found no settings to remedy.
The version is completely outdated, and long unmaintained.
