Prior to xdg-output v3, that wasn't an issue because the +compositor is required to send an xdg_output.done event after sending +xdg_output properties. + +Starting with v3, the compositor may choose not to send an +xdg_output.done event after sending xdg_output properties. Therefore, +as is, QtWayland may announce an output with bad logical geometry or +even worse without name assigned by the compositor. + +Unfortunately, that breaks applications such as plasmashell. Plasma uses +output names as a criterion to determine what kind of contents should be +displayed on a particular output. + +In order to fix the initialization sequence, this change makes every +QWaylandScreen track processed events. After all required events have +been received, the screen can be announced to the rest of Qt. + +Change-Id: If5da747edd7af277ec1364cbea105c6994f47402 +Reviewed-by: David Edmundson <davidedmundson@kde.org> +(cherry picked from commit 69ea480f2e53ad4a5bbca78cde044eb8d4c48896) + +Original Ticket: https://codereview.qt-project.org/c/qt/qtwayland/+/347774 +CCBUG: 435124 +--- + src/client/qwaylandscreen.cpp | 32 +++++++++++++++++++++++--------- + src/client/qwaylandscreen_p.h | 10 ++++++++-- + 2 files changed, 31 insertions(+), 11 deletions(-) + +diff --git a/src/client/qwaylandscreen.cpp b/src/client/qwaylandscreen.cpp +index 6cb337de..7c2d9be3 100644 +--- a/src/client/qwaylandscreen.cpp ++++ b/src/client/qwaylandscreen.cpp +@@ -72,7 +72,7 @@ QWaylandScreen::QWaylandScreen(QWaylandDisplay *waylandDisplay, int version, uin + qCWarning(lcQpaWayland) << "wl_output done event not supported by compositor," + << "QScreen may not work correctly"; + mWaylandDisplay->forceRoundTrip(); // Give the compositor a chance to send geometry etc. +- mOutputDone = true; // Fake the done event ++ mProcessedEvents |= OutputDoneEvent; // Fake the done event + maybeInitialize(); + } + } +@@ -83,14 +83,25 @@ QWaylandScreen::~QWaylandScreen() + zxdg_output_v1::destroy(); + } + ++uint QWaylandScreen::requiredEvents() const ++{ ++ uint ret = OutputDoneEvent; ++ ++ if (mWaylandDisplay->xdgOutputManager()) { ++ ret |= XdgOutputNameEvent; ++ ++ if (mWaylandDisplay->xdgOutputManager()->version() < 3) ++ ret |= XdgOutputDoneEvent; ++ } ++ return ret; ++} ++ + void QWaylandScreen::maybeInitialize() + { + Q_ASSERT(!mInitialized); + +- if (!mOutputDone) +- return; +- +- if (mWaylandDisplay->xdgOutputManager() && !mXdgOutputDone) ++ const uint requiredEvents = this->requiredEvents(); ++ if ((mProcessedEvents & requiredEvents) != requiredEvents) + return; + + mInitialized = true; +@@ -276,9 +287,8 @@ void QWaylandScreen::output_scale(int32_t factor) + + void QWaylandScreen::output_done() + { +- mOutputDone = true; +- if (zxdg_output_v1::isInitialized() && mWaylandDisplay->xdgOutputManager()->version() >= 3) +- mXdgOutputDone = true; ++ mProcessedEvents |= OutputDoneEvent; ++ + if (mInitialized) { + updateOutputProperties(); + if (zxdg_output_v1::isInitialized()) +@@ -339,7 +349,7 @@ void QWaylandScreen::zxdg_output_v1_done() + if (Q_UNLIKELY(mWaylandDisplay->xdgOutputManager()->version() >= 3)) + qWarning(lcQpaWayland) << "zxdg_output_v1.done received on version 3 or newer, this is most likely a bug in the compositor"; + +- mXdgOutputDone = true; ++ mProcessedEvents |= XdgOutputDoneEvent; + if (mInitialized) + updateXdgOutputProperties(); + else +@@ -348,7 +358,11 @@ void QWaylandScreen::zxdg_output_v1_done() + + void QWaylandScreen::zxdg_output_v1_name(const QString &name) + { ++ if (Q_UNLIKELY(mInitialized)) ++ qWarning(lcQpaWayland) << "zxdg_output_v1.name received after output has been initialized, this is most likely a bug in the compositor"; ++ + mOutputName = name; ++ mProcessedEvents |= XdgOutputNameEvent; + } + + void QWaylandScreen::updateXdgOutputProperties() +diff --git a/src/client/qwaylandscreen_p.h b/src/client/qwaylandscreen_p.h +index df1c94f2..050cfdc0 100644 +--- a/src/client/qwaylandscreen_p.h ++++ b/src/client/qwaylandscreen_p.h +@@ -116,6 +116,13 @@ public: + static QWaylandScreen *fromWlOutput(::wl_output *output); + + private: ++ enum Event : uint { ++ XdgOutputDoneEvent = 0x1, ++ OutputDoneEvent = 0x2, ++ XdgOutputNameEvent = 0x4, ++ }; ++ uint requiredEvents() const; ++ + void output_mode(uint32_t flags, int width, int height, int refresh) override; + void output_geometry(int32_t x, int32_t y, + int32_t width, int32_t height, +@@ -148,8 +155,7 @@ private: + QSize mPhysicalSize; + QString mOutputName; + Qt::ScreenOrientation m_orientation = Qt::PrimaryOrientation; +- bool mOutputDone = false; +- bool mXdgOutputDone = false; ++ uint mProcessedEvents = 0; + bool mInitialized = false; + + #if QT_CONFIG(cursor) +-- +2.36.0 + +From 95a139413337bb92a9dbbbd95f61e52cc1f43649 Mon Sep 17 00:00:00 2001 +From: Jaeyoon Jung <jaeyoon.jung@lge.com> +Date: Mon, 15 Feb 2021 08:31:06 +0900 +Subject: [PATCH 02/38] Fix issue with repeated window size changes + +Check if the new window size is different from the size requested +previously before calling wl_egl_window_resize.
