general play using menu, I'd earlier added another panel, updates were downloading & installing and whilst using menu crash appeared.

No unusual behavior was noticed.

Xubuntu 19.10 (daily) install from a very recent QA-Test install booted for a test of something related to a ask-ubuntu question.

This is dell optiplex 780 so not the machine mentioned in a prior comment, I'd just logged in and was trying to adjust my right display (it's portrait-left tilted) and crash was reported.

(Something isn't right; I thought I'd adjusted my displays to match my setup; but it's responding as if I only have a single display connected)

Is this issue still occurring in a recent supported release (focal, impish, jammy)?
