Git commit 359411e7bbd16f253025e31b58919512eb5f80e1 by Tor Arne Vestbø (on behalf of Jonas Karlsson) on 07/08/2026 at 11:31..
Windows/D3D11: stop fallback timer when DXGI vsync takes over

QWindowsWindow::requestUpdate() falls back to QPlatformWindow's 5ms
timer until DXGI vsync becomes available (e.g. before the D3D11
swapchain is created). QPlatformWindow::windowEvent() only stops that
timer when hasPendingUpdateRequest() is false, so if a request is
still pending at the moment DXGI takes over, the timer is left
running alongside the DXGI vsync callbacks. The stale timer then
triggers concurrent deliverUpdateRequest() calls, hitting
Q_ASSERT(hasPendingUpdateRequest()) and causing excess polishAndSync()
calls that make animations jerky.

This is reproducible with Qt Quick 3D: an animated QQuickItem placed
inside a Node triggers an early requestUpdate() (via
QQuick3DItem2D::addChildItem()) before D3D11 is ready, starting the
fallback timer that later races with DXGI vsync.

Stop the fallback timer from QWindowsWindow::requestUpdate() once DXGI
vsync is available. QPlatformWindow::d_ptr is protected, so no new API
is needed for this.

harmonyos: fix empty lines around includes

This is a preparatory change for normalizing includes in harmonyos
platform code.

Some include blocks are either using double empty lines or are glued to
other code. Fix this by wrapping all include blocks with a single empty
lines.

harmonyos: add missing includes

This is a preparatory change for normalizing includes in harmonyos
platform code.

There are two files, which are missing includes:
  * qohoskeymodifiers: missing qnamespace.h include
  * qohospdfprintengine: missing include for Print_* types

These includes currently resolve due to favourable order of includes,
however, when we normalize the includes in platform code, they will no
longer resolve and fail at compile time.

Note, that this commit doesn't add includes, which are included
indirectly, through other include files.

harmonyos: normalize usage of <QtModule/file.h> includes

This is preparatory change for normalizing the includes for harmonyos
platform code.

There are still includes of <QtType> or <QtModule/QtType> instead of
<QtModule/file.h>. Allign these includes with Qt coding conventions.

rcc: Add security markers

While rcc itself is a build tool and thus marked as "insignificant",
rcc.h as well as rcc.cpp are also duplicated in designer's sources. Due
to this special case, these files are marked "significant".

uic: Add security markers

uic is a build tool, so its sources are marked "insignificant". The
exception are ui4.h and ui4.cpp, which implement the .ui XML parser and
are generated by qttools/src/designer/data/generate_ui.py from ui4.xsd.
The same generator emits qttools/src/designer/src/lib/uilib/ui4{.cpp,_p.h},
which is compiled into Qt UI Tools and parses .ui files at application
runtime. Due to this special case, these files are marked "significant".

Fix flaky tst_QDnsLookup::lookupNxDomain on Windows 11

tst_QDnsLookup::lookupNxDomain used to be fail on Windows when executed
more than once as something was incorrectly being cached by Windows
causing the test fail.

This is no longer the case.
Remove the firstRun logic that expected subsequent executions of the
test to fail.
