QXcbWindow::create() bound the window's size to windowMinimumSize(),
after its size had been inherited from parent().
QPlatformWindow::setGeometry() was called before that sanity check.
When a fullscreen window is re-mapped from a deactivated screen to the
remaining screen, the call to QPlatformWindow::setGeometry() assigns
an invalid QRect to QPlatformWindowPrivate::rect
The negative int values x2 and/or y2 cause
QXcbBackingStoreImage::flushPixmap to address unmapped memory and
crash.
This patch moves the call to QPlatformWindow::setGeometry() from
before to after bounding to a minimum value. That assures a valid
rectangle to be assigned in all cases.
The device would be deleted before the image format handler, and hence
be a dangling pointer that could easily cause a crash if the handler
or codec would access it on destruction, e.g. for cleanup.
Make it possible for non-letter-keys with Latin 1 symbols (`, !, @ etc.)
to participate in shortcuts also, when the keys generate national
symbols on non-Latin layout.
For example, in Russian layout, "`" key generates cyrillic "ё" letter of
national alphabet, so shortcuts with the key should still work
regardless of the actual layout.
Some netWmState needs to be set during unmap/hide(), which is too
difficult to follow, and causes m_mapped status out of sync very easily
sometimes, which we had tried in e946e6895a8517a887ac246905e0769edd766fcc .
Destroy the xcb window and recreate new could make the thing
much easier. This practice is also used in other platforms, such
as cocoa plugin.
In Qt 4, the platform window was destroyed and re-created in this
situation on all platforms, which was not ported into Qt5.
See also the code between setWinId(0) and createWinId() in
QWidgetPrivate::setParent_sys() in qwidget_x11.cpp/qwidget_win.cpp/
qwidget_mac.mm.
It clears the duplicate show() and hide() too aggressive in
handleDeferredTasks() and can cause visible states out of sync between
qt and system(x11) when user switches visible on and off very
frequently.
Qt wayland platform plugin has improved quite a lot and it is now pretty
much usable on Gnome. It also improves user experience a lot on HiDPI
displays.
On some platforms, such as X11 and Wayland with some compositors,
QMenu could be a popup window, which should be set a transient parent
to get relative position, which is requested by Wayland.
Added transientParentWindow() for QMenuPrivate like QDialogPrivate.

openssl3 uses uint64_t for the options argument in SSL_CTX_set_options,
older ones used long.
sizeof(long) is not the same on any platform as sizeof(uint64_t)
Unless "." (or the empty string) is in $PATH, we're not supposed to find
executables in the current directory. This is how the Unix shells behave
and we match their behavior. It's also the behavior Qt had prior to 5.9
(commit 28666d167aa8e602c0bea25ebc4d51b55005db13). On Windows, searching
the current directory is the norm, so we keep that behavior.
This commit does not add an explicit check for an empty return from
QStandardPaths::findExecutable(). Instead, we allow that empty string to
go all the way to execve(2), which will fail with ENOENT. We could catch
it early, before fork(2), but why add code for the error case?

The MariaDB-connector-c version 3.2 and MariaDB server version 10.6
cooperate to avoid re-transferring the query metadata, so the fact that
we were modifying it was causing it to improperly decode the DATETIME
data types into string, as we had asked. We ended up with a 7-byte
string that was actually the date binary-encoded.
When calling setStyleSheet with property qproperty-styleSheet,
QStyleSheetStyle::polish will call QStyleSheetStyle::setProperties,
and then QStyleSheetStyle::setProperties goes on to call setProperty.
Because there is property qproperty-styleSheet, it will update
stylesheet by calling QStyleSheetStyle::polish.
This causes the recursive call to crash.
The fusion style did ignore the QIcon::On icon because it reset
State_On to avoid the visual shift of a pressed button.
But it's not needed to reset this flag - the shift does not happen
because the fusion style does return 0 as offset for
PM_ButtonShiftHorizontal/PM_ButtonShiftVertical so no shifting will
happen.
When multiple globs match, and the result from magic sniffing is
unrelated to any of those globs, globs have priority and one of them
should be picked up.
