Hi Sir,

My customer found that when moving cursor , CPU usage will pull high dramatically (over 50%)

He want to know is HW or SW decode when moving cursor .

Thanks!

Environment : IMX6 DL Android 6.0.1_2.1.0

I see surfaceflinger process takes significant CPU usage in case of cursor movement.
Please make sure that hardware cursor drawing is enabled. Display Processor of i.MX has an option for hardware cursor.

Have a great day,
Victor
