CEF/Chromium initialization and the creation of the first browser may take a few seconds for several reasons like proxy detection, antivirus scan, etc.
I will investigate if killing the app at that moment is a supported scenario in CEF.

Issue seems to have been fixed by CEF 125.0.22

Sometimes Chromium can detect when the application is closing and it will close the child processes automatically.
Applications should follow the destruction steps described in the code comments of the demos and stopping the debug session skips those steps.
CEF 125 has many internal changes and it might have changed the way it detects when the app is closing.
I built TabbedBrowser2 (32 bits) with Delphi 12 and killing the app from the task manager left no orphan processes but stopping the debugger left one process dangling.
I'll leave this issue open for the moment to see if there's some kind of Windows message or event that notifies the app that the debugging session was closed and then follow the destruction steps in order to close the child processes correctly.

Erratum: it was from Delphi 12 not Delphi 10 for me
I have tried runs with or without gpu, with or without pre-existing cache folder, no effect AFAICT.
However there seems to be a time sensitivity related to initialization: when starting the TabbedBrowser2, if killing the main process in the first few seconds, there is pretty much always a leftover process.
When waiting maybe 15 seconds, there is no more leftover process, even if the browser frame is very active (I tried running webgl experiments and html5 games).
I went back to SimpleBrowser2 demo, and when killing it swiftly, it exhibits the same issue.
So this may be that the render process is not yet ready to detect or react to a kill notification early on, not sure if that's on the Delphi or the CEF side though.
