--disable-gpu flag is not working in simple browser application .

Rajesh_M

I am trying to disable the gpu in simple browser application using the --disable-gpu flag but the usage of CPU remains same before using this flag and after using this flag when measuring using top command. The Qt verison I am using is 6.4 and chromium version is 94 . When I am using the --disable-gpu flag ,the changes are getting reflected in the chrome://gpu by changing the status to softwareonly, Hardware acceleration disabled.
I tried to play a youtube video and checked the top command for above. The graphics backed is eglfs. One last question is how can we conform whether the application is using the gpu or not?
Can anyone suggest me some ideas to disable the gpu in eglfs in simple browser .

When using the --disable-gpu flag the following is the output
