Using Misc Console as Konsole's font, the fonts seems to be shifted down and the last line is not rendered. This happens with Qt 4.8, but not with 4.7 and only when Bi-di rendering is disabled in the konsole profile. See https://bugreports.qt.nokia.com/browse/QTBUG-22270 . I tried to reproduce with a simple const QChar LTR_OVERRIDE_CHAR( 0x202D ); p.drawText( r, 0, LTR_OVERRIDE_CHAR + text); in a QWidget's paint event, but could not, probably Konsole does something else as well. If you can narrow down this to a simple test case, please update my bug report for Qt and reopen it.
This sounds similar to or related with bug 280896.
