sometime mess up, not at the end of line but inputed character will in beginning of line and cover character already there I meet a few time already, the windows maxmized, I input some command within the windows, far from end of line, it break line and any character I input will show up at the beginning of current line(not break in to new line) I has the picture to show this but seem can't upload here, you can see it here http://www.flickr.com/photos/williamherry/8639965850/in/photostream Reproducible: Couldn't Reproduce
Created attachment 86333 [details] video: Reproducing bug with long (multiple lines) command This bug is entirely reproducible. Here it is on 4.11.5 (Konsole 2.11.3) (Ubuntu). Observed same or similar on 4.12.2 (Manjaro). To reproduce: 1) Use a command whose output doesn't end with a newline (e.g. echo -n foobar). 2) Type in a command that will span well over onto the next line. You'll see the cursor jump back to the beginning of the line while you're typing.
Created attachment 86336 [details] video: Related inserting of command into the middle of prompt Here's a related case. To reproduce, enter "echo -n foobar", then press up, then home. You'll see the cursor is in the wrong place. If you start typing, the end of your prompt starts getting pushed to the right as if it were part of your command, but eventually the end of your prompt gets overwritten and suddenly you're typing up next to the previous command. I've see this on both distros mentioned above. There's some other weirdness I could mention - like on my box, if I were to type an "e" there where I typed a "t" (the word "this"), I get an "o" instead. Your mileage may vary on that one.
Reopen if you can still reproduce the issue in the description of this report. For the issue(s) in comment#1 and comment#2, please open a separate report if you can still reproduce it.
