RStudio Desktop and QtWebEngineProcess on macOS using very much CPU

Thanks for the bug report! Can you provide any other information?

  • Does it occur in all projects? What about in the 'empty' project (ie, if you close the current project)?

  • Does it seem to depend on what is visible in the IDE surface?

  • Does switching to software rendering make a difference?

The QtWebEngineProcess executable is primarily responsible for rendering things on-screen, so I would normally only expect something like this if e.g. you were using large HTML widgets within the IDE, for example.

Any other information you can provide will be helpful.
