() 904569 1 yoon 2013-06-28 05:04:08 -0700 I've found the problem of this failure. When QtWebPageSGNode destructed, CoordinatedGraphicsScene clears its all of resources including m_registeredLayers during purgeGLResources but CoordinatedLayerTreeHost clears just backingstores. To fix this failure, I think we need to destruct all of CoordinatedGraphicsLayers in CoordinatedLayerTreeHost during purgeBackingStore. 975752 2 jturcotte 2014-02-03 03:26:26 -0800 === Bulk closing of Qt bugs === If you believe that this bug report is still relevant for a non-Qt port of webkit.org, please re-open it and remove [Qt] from the summary.
