You can see in the screenshot that the "Show CPU usage" feature from Developer Options only shows processes involving com.android.systemui, instead of a list of all top processes. This is likely a result of security enhancements related to isolation. It seems to me that the built-in developer tool should be allowed to break the rule. However, if this is the new normal, I suggest the list be removed from this overlay, since seeing only com.android.systemui processes is not useful.

Third-party applications cannot see any other processes either. In the screenshot, you can see Cool Tool at the top reporting that it is the highest-usage process, and OS Monitor reports only itself as well.

Due to API finalization it is probably too late to fix the problem by creating an API to allow such information access, so third-party process monitors are screwed, but in my opinion, the built-in developer option feature should be fixed.
