A very simple solution i found, if it is the same problem, > to hide control rig (i do it, to see if the limbs/fingers are in correct spot, cuz rig fills the screen), is to, -
If you press Shift + 1 you will go to selection mode, which hides the rig, and then in top > Edit > Editor Preferences > Type in search , animation ‘’ and set the shortcut, ALT + T, that’s the one that works for me. Wanted to make it Shift + T but won’t work.
This way, you can quickly toggle on and off Control Rig while working on your anim.
