The child process prevents display mode changes

My project uses the cef109 version and has problems with the cef gpu and utility processes created by default preventing display mode changes, as does cefsimple, but not cefclient. How can I fix this

What OS? How are you trying to change display mode?

Mine is a windows laptop, the default display mode is automatically selected, when I launch games such as pubg and COD19, should want to switch to NVIDIA GPU only mode, at this time my cef child process blocks it; Similarly, my manual automatic selection and NVIDIA GPU-only mode switching in the NVIDIA control panel will also trigger

How does it behave with Google Chrome? You may need to update your CEF version to make an equivalent comparison.
