    Description

      Qt Creator's QML Profiler has a QML-based UI which is loaded when Qt Creator starts.
      The first time the application launches, 22 .qmlc files are generated in the cache directory. On the second launch, 13 .qmlc files get regenerated/modified. The first and second versions have the same file name and file size, only a small difference...

      The third and further launches of Qt Creator do not write/modify any qmlc files.
      The first and second launches were done with clean settings pathes:

      bin\qtcreator.exe -noload all -load QmlProfiler -settingspath c:\temp\cleanpath1
bin\qtcreator.exe -noload all -load QmlProfiler -settingspath c:\temp\cleanpath2

      These are the concrete files which get written

      First run:
  qrc:/tracing/TimelineText.qml
  qrc:/tracing/Detail.qml
  qrc:/tracing/ImageToolButton.qml
  qrc:/tracing/RangeDetails.qml
  qrc:/tracing/TimeDisplay.qml
  qrc:/tracing/RangeMover.qml
  qrc:/tracing/SelectionRange.qml
  qrc:/tracing/TimelineRulers.qml
  qrc:/tracing/RowLabel.qml
  qrc:/tracing/CategoryLabel.qml
  qrc:/tracing/TimeMarks.qml
  qrc:/tracing/TimelineLabels.qml
  qrc:/tracing/ButtonsBar.qml
  qrc:/tracing/TimelineContent.qml
  qrc:/tracing/SelectionRangeDetails.qml
  qrc:/tracing/Overview.qml
  qrc:/tracing/MainView.qml
  qrc:/tracing/ImageToolButton.qml
  qrc:/tracing/RangeDetails.qml
  qrc:/tracing/FlameGraphDelegate.qml
  qrc:/tracing/FlameGraphView.qml
  qrc:/qmlprofiler/QmlProfilerFlameGraphView.qml

Second runs:
  qrc:/tracing/ButtonsBar.qml
  qrc:/tracing/TimelineContent.qml
  qrc:/tracing/SelectionRangeDetails.qml
  qrc:/tracing/TimeDisplay.qml
  qrc:/tracing/Overview.qml
  qrc:/tracing/TimelineRulers.qml
  qrc:/tracing/TimeMarks.qml
  qrc:/tracing/RowLabel.qml
  qrc:/tracing/CategoryLabel.qml
  qrc:/tracing/TimelineLabels.qml
  qrc:/tracing/MainView.qml
  qrc:/tracing/FlameGraphView.qml
  qrc:/qmlprofiler/QmlProfilerFlameGraphView.qml

      I attached the two versions of the cache directory as qmlc_caches.zip.
