      It should be possible to temporarily release resources like OpenGL contexts for both WebEngineView and QWebEngineView objects that are currently not shown / hidden.

      Use case

      Tabbed web browsers can have an almost arbitrary number of tabs open, but the content of only one tab is visible at a time. Anyhow, the most straightforward solution - having a WebEngineView in each tab - also means that every tab binds some resources, most prominently up to 3 OpenGL contexts and a renderer process.

      It would be great that such a browser could just free resources for a tab that is not used since a while, or if the resources are exhausted.
