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.
