Qml WebEngineView: WebGL: CONTEXT_LOST_WEBGL upon returning from sleep

XMLWordPrintable

    • Windows

      WebEngineView consistently reports CONTEXT_LOST_WEBGL (along with a wall of similar errors) upon returning from sleep on Windows. The WebEngineView itself seems to function to some extent but any content is completely frozen and unresponsive.

      Reloading the page doesn't seem to have much effect either but destroying the webengineview and creating a new one resolves the issue.

      Steps to reproduce:

      1. Run the attached project
      2. Set your machine to sleep
      3. Come back from sleep
      4. Observe the application output
