Package: libqt5core5a
Version: 5.15.6+dfsg-2
Severity: wishlist
X-Debbugs-Cc: bernhardu@mailbox.org


Dear Maintainer,
I experienced since about a month ago sometimes crashes in applications
running in fullscreen, when doing display configuration changes
or lately when waking up the screen from power saving.
(See below for an example backtrace.)

I opened these upstream bug reports, where the
Qt bug received a patch hopefully fixing this issue:

  https://bugs.kde.org/show_bug.cgi?id=461723
  https://bugreports.qt.io/browse/QTBUG-109226
  https://code.qt.io/cgit/qt/qtbase.git/commit/?id=6a3627b6c5aa5109a80024f3d7b0f938504f7ffe
  (Unfortunately it looks like the qt-5.15 cerry-pick is not publicly visible.)

I create this bug also to ask how chances are that this
commit reaches Qt before or during the freeze period?

Kind regards,
Bernhard
