During test with the attached source codes, measuring memory usage using heaptrack, memory leak is suspected.
When Layer.enable is set to true, and visible is set to false, model of Repeater changes condition.
(start with true and after some times (e.g 5sec) changed it to false will be same).
It was observed that memory usage increased in a functions in our environment.
- QSGBatcherRender::Allocator<QSGBatcherRenderer::Element, 64>::allocate()
- layer.enabled = true
- visible = true
- model of Repeater changes
- Timer 5sec changed visible from true to false.
There were similar results was observed from version 6.2.2 to 6.9.1.
Below screenshot could find attached heaptrack result file (zst extention)
expected result: stable memory usage.
actual result: memory usage increases.
// Main.qml import QtQuick Window { id: rootWindow visible: true width: 400 height: 400 // Timer { // interval : 5000 // running: true // repeat: false // onTriggered: { // case1Area.visible = false // } // } Rectangle { id: case1Area anchors.centerIn: parent width: 350 height: 350 color: "lightgray" layer.enabled: true visible: false ListModel { id: gforceModel } Timer { interval: 20 running: true repeat: true onTriggered: { gforceModel.append({ x: Math.random() * (case1Area.width - 20), y: Math.random() * (case1Area.height - 20) }) if (gforceModel.count > 2) { gforceModel.remove(0) } } } Repeater { model: gforceModel delegate: Image { width: 20 height: 20 source: "image_0001.jpg" x: model.x y: model.y } } } }
