In vi, erasing long lines will cause the text to become garbled, somewhat. I have to redraw the video buffer by scrolling back and forth and sometimes the input won't be in the same place, so it looks like I'm overwriting good text and I have to quit/relaunch.
In typing long commands, pressing backspace will result in the cursor moving upwards in a stair-like manner.
It's not amazingly crippling but it's rather annoying. Somewhat hard to describe textually but it's more or less that.
Maybe I could recompile it from source, I actually haven't tried. It could also be an issue with vidcontrol but the same configuration worked fine on 8.2-R-p6.
I can probably figure it out but if anyone else has experienced it...
