This +leaves a logic bug that we can have the updatePending flag set but +never cleared. + +If we have two windows, this leaves the other window still updating +normally, but lastDirtyWindow will always be false and we never call +endSync. + +This results in an effective memory leak of all textures. + +This patch resets the flag on hide() a move that can be considered safe +given the show() method will reset this flag anyway. + +Change-Id: Iab0171716e27e31077a66b5e36a00bf28a2e7a8c +Reviewed-by: Kai Uwe Broulik +Reviewed-by: Qt CI Bot +Reviewed-by: Dominik Holland +Reviewed-by: Aleix Pol +Reviewed-by: Andy Nichols +--- + src/quick/scenegraph/qsgrenderloop.cpp | 5 ++++- + 1 file changed, 4 insertions(+), 1 deletion(-) + +diff --git a/src/quick/scenegraph/qsgrenderloop.cpp b/src/quick/scenegraph/qsgrenderloop.cpp +index 60f3538662..2eaed497ef 100644 +--- a/src/quick/scenegraph/qsgrenderloop.cpp ++++ b/src/quick/scenegraph/qsgrenderloop.cpp +@@ -305,6 +305,8 @@ void QSGGuiThreadRenderLoop::hide(QQuickWindow *window) + { + QQuickWindowPrivate *cd = QQuickWindowPrivate::get(window); + cd->fireAboutToStop(); ++ if (m_windows.contains(window)) ++ m_windows[window].updatePending = false; + } + + void QSGGuiThreadRenderLoop::windowDestroyed(QQuickWindow *window) +@@ -494,7 +496,8 @@ QImage QSGGuiThreadRenderLoop::grab(QQuickWindow *window) + + void QSGGuiThreadRenderLoop::maybeUpdate(QQuickWindow *window) + { +- if (!m_windows.contains(window)) ++ QQuickWindowPrivate *cd = QQuickWindowPrivate::get(window); ++ if (!cd->isRenderable() || !m_windows.contains(window)) + return; + + m_windows[window].updatePending = true; +-- +2.16.3 + -- cgit v1.2.3
