When playing back footages in anamorphic pixel aspect ratio using cuda/metal it displays wrongly.
Anamorphic footage with 2:1 pixel aspect ratio is stretched 2x horizontally when using cuda and metal renderer in project settings.
I have to use software in order to display it correctly.
Interestingly on windows it looks normal IF footage scale is 50% and above. but below 50% it looks stretched again.
Windows cuda with rtx2080,
Winodws cuda with rtx2070
Mac Pro metal with AMD D700 Pro
All using latest version of premiere pro.
