Aspect ratio cropmarks made of text dots- visible even with global draw OFF

[kgv5]

Recently i started to use fps override mode quite often to capture 36-38fps in 1080p 2,35:1 aspect. I get about 18-20 seconds which is quite usable for me (with MLV-lite even 30 seconds). Thing is that global draw must be turned OFF to avoid damaged frames - 35-36 is max with global draw ON (damaged frames happens but very rarely), 37-38 i am getting couple corrupted frames in every shot with GD ON (i am using sandisk extreme pro 128gb 160mb/s) It is hard to frame 2,35:1 with global draw OFF, i marked my screen with tape to help with framing. When GD is OFF we still have some basic info on the screen like number of frames recorded etc. So i thought maybe devs could add to those existing dials two rows of white dots on the screen (.........................) in place where 2.35:1 cropmarks would be with GD ON. What do you guys think? Is it possible to have this outside of global draw?
