This bug was fixed in the package ubuntu-release-upgrader - 1:18.04.6
---------------
ubuntu-release-upgrader (1:18.04.6) bionic; urgency=medium
* DistUpgradeFetcherKDE.py:
- ensure theming is correct across all Qt versions and Plasma versions
- drop unused openUrl helper (replaced by QUrlOpener)
* QUrlOpener.py:
- make sure to pass --set-home to sudo when dropping back to user, prevents
browsers from getting confused which HOME to use
* DistUpgradeViewKDE.py:
- force KDE theming for Qt5
- fix icon & pixmap lookup by running them throw a compatibility helper
using either Qt3/4 static lookup or Qt5 theme-based lookup (theme is
determined by the QPA ideally)
- let name mangling use os-release' PRETTY_NAME if present
- do not resize windows, adjustsize() them (same as resize albeit readable)
- introduce an override for QWidget.adjustSize() which prevents adjustment
iff the window is maximized. as noted in the documentation adjusting a
maximized yields unexpected results due to a control mismatch between
X11 window managers and Qt (in short: Qt cannot unmaximize, so adjustsize
does nothing useful in this case and in fact causes only part of the
window to be marked dirty by Qt causing sever rendering artifacts)
