Comment 2 ninjalj 2021-05-01 22:33:20 UTC 
Sorry about that. I'm to blame for this one.

How do you reproduce the bug? I have a fix at https://invent.kde.org/utilities/konsole/-/merge_requests/388 but it would be nice to really make sure that it fixes your case.
Comment 3 Aleix Pol 2021-05-02 01:24:39 UTC 
It's not that easy to reproduce, the patch makes sense though.
Comment 4 Bug Janitor Service 2021-05-02 12:31:00 UTC 
A possibly relevant merge request was started @ https://invent.kde.org/utilities/konsole/-/merge_requests/389

Fix crash on resize while doing other things

Commits 9ffe33a27a8720aba2f066fef0b0bdb3efcbea72 and
4352df00d9fd66f5333421f328a2c5618eda60b7 introduce and use a
getScreenLineColumns(line) method to provide support for DECDWL
(Double-Width) lines.

It turns out that under some conditions on resize Screen::_cuY (the
current cursor Y position) and ScreenWindow::endWindowLine() can have
different ideas of how many lines the terminal has.

A test that asserts:

 - while [ true ]; do echo -e "\e[?1047h";  done
 - Resize the window, making it smaller
