Keep new clients hidden until they utilise the GPU.

Not sure we need to do it at this level and not instead at presentation
time.

My goal was just presentation :(

Something like this would be presentation time:

diff --git a/tools/intel_gpu_top.c b/tools/intel_gpu_top.c
index 60ff62d28e5d..f7c5cc3bf19f 100644

                lines++;

                printf("%6u %17s ", c->pid, c->print_name);

But it worries me a bit to do it by default.


Plus, in default sort mode they would be at the end of the list,
so behind the more active clients. Or you go into sort by id and they
annoy you there?

No. I had a bunch of "Xorg" when launching steam which never became
anything. So I guess just a bunch of dlopen("libgl") spawing a bunch of
clients that we never used for anything more than gl[X]GetString, but
leaked the fd.

But they were at the end, so potentially even cut of if enough interesting clients? Or you actually sorted by id? Or something else is broken?


[Why does steam need 10% of the gpu to update an icon on the toolbar
which is hidden while minimised? Why do games sit in static menus at
100% gpu? Why?]

Yep, I have this issue with animated KDE tray icons. :I
