Bug ID: 442330
Summary: Terminal output shifts one line up/down on window
minimize/maximize
Product: konsole
Version: 21.08.1
Platform: Archlinux Packages
OS: Linux

Recorded behavior
SUMMARY
After sequence of terminal window minimization/maximization, there's a glitch
causing terminal output content to temporarily move one line down/up.
When switching to other app window and back to konsole, window content stays
intact.
This movement of line down/up happens only when terminal is scrolled to he
bottom (last line and prompt is visible). When we scroll the content somewhere
up, behavior is slightly different: bottom line temporarily shows proper line
that should be here, but after a moment it's erased with empty line.
Screen recording is attached.
STEPS TO REPRODUCE
1. Fill the terminal window with some content that fills it vertically and is
scrollable verically
2. Try to minimize/maximize konsole window in various vertical scroll
positions.
OBSERVED RESULT
As described, see attachment that contains recorded behavior as video.
EXPECTED RESULT
Steady window content.
