FWIW, I can duplicate this behavior in gnome-terminal. All I need to do is Edit the
Profile Preferences and pick "Custom font" and Monospace Regular with a size
Hmmm. Also, if I recall, I experienced these three strange phenomena:
1. Some color combinations were worse, intermittently. I think the
yellow text on black background was the worst. Switching to a different
tab and back to the first one again would sometimes clear the problem.
2. Sometimes, upon scrolling the text in Konsole, and even scrolling up
and then down again in vim, it would superimpose an entire, screen wide
underline upon a line of text. And at times even two.
3. Much more rarely I would even see some character overstriking with
different letters, but slightly offset up or down but a pixel or two.
I quit investigating because I now get the correct representation 99%
(NOT 100, sigh) of the time.
