With the current revision of libQt6Gui6-6.4.2-150500.3.7.4 from the official
openSUSE repos, the qt6-creator-9.0.2 hangs when showing the Issues pane and
consumes all memory in an infinite loop. The bug is the same as described on
https://bugreports.qt.io/browse/QTCREATORBUG-28593 and connected with
https://bugreports.qt.io/browse/QTBUG-109474

This is a regression in Qt6Gui cased by patch
https://codereview.qt-project.org/c/qt/qtbase/+/435080 for Qt-6.5 branch. As
per changelog, this patch was also applied to the qt6-base-6.4.2 from the
"Updates from SUSE Linux Enterprise 15" repository (source file
`0002-QTextLayout-fix-maximumWidth-for-a-text-containing-line.patch`). Thus,
the problem appears now in Qt-6.4 branch including qt6-creator hang.

Downgrading libQt6Gui6-6.4.2 to the original revision of
libQt6Gui6-6.4.2-150500.1.14 from the Main OpenSUSE repository do resolves the
issue with Qt6-creator.

The problematic qt6base patch 435080 was superseded in the upstream via
https://codereview.qt-project.org/c/qt/qtbase/+/453906 . Hope, this can be
backported to the 6.4.2 as well. Or, the bad 435080 patch can be just removed
altogether.
