QWidget::restoreGeometry() is calling QWidget::move() with restoredFrameGeometry, which internally calls setGeometry() and sets positionPolicy = QWindowPrivate::WindowFrameExclusive, which is invalid: restoredFrameGeometry is WindowFrameInclusive geometry. QPA plugins rely on correctly set policies when interpreting x,y. QWidget::move() was not designed for this AFAICT, so making it to accept frame geometry is no-op. It is widely used legacy code, changing it could cause regressions. Save/restore API was introduced in Qt 4.2, at that time we did not have APIs like QWindow::setFramePosition(), so its unclear why geometry() was not stored instead. The documentation also is somewhat unclear: "[..] save the geometry when the window closes [..]" Frame or client geometry? It does not specify. And from the code we see that frame geometry was passed as client geometry, not making the original intention clearer. Besides that, restoreGeometry() is full of other undocumented assumptions where to place windows and when to fail (fortunately its easy to write your own save/restore logic). Added a Qt 6 note in the source code. What this patch changes: Now we store geometry() in saveGeometry() and use that value in restoreGeometry() by setGeometry(). This does not cause any behavior difference in window positioning (tst_QWidget::saveRestoreGeometry still works). Geometry restored from data saved with earlier versions of saveGeometry() might be positioned at: x + leftMargin, y + topMargin. This patch makes tst_QWidget::saveRestoreGeometry to always fail instead of being flaky. Blacklisting for XCB instead of selected distros. Also enabled excluded code paths for XCB on tst_QDockWidget::restoreDockWidget(). It does not seem to be flaky, maybe it was in 2015, but lot of things have changed since then.

README
This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
