Cool, Yes, here is the way:
Enable ADTG Registers from Debug Tab in ML settings --> Press Q button --> Select Advanced, Enable ENGIO Registers, Exit ML menu, Press Menu Button twice, get into x5 Mode then x10 Mode and get back to 1080p Mode then get into x5 Mode again --> Go to ADTG Registers --> Press on "Everything" --> Select "Modified from now on" --> Exit ML Menu, Now go to x10
Now you got the registers between x5 and x10 mode, start tweaking each register, until you find the stretching ones if there any on 6D, You can press Q button to return register to original value if something happen.
I'd like to take a look in the registers, if you could provide a LOG, same steps above, after that press "Log registers now" from Advanced menu, a file with name adtg.log will show in ML/LOGS folder in the SD Card, you can share this file here publicly.
Good Luck!
