Gave strange results - 512x512 - all images became scanlined and faint after scaling

Hi, what is your gpu specs?

Hi - it's an Nvidia1060, 3GB

Strange, all Nvidia gpus are compatibile.  Are you on latest driver?

Did you tried CPU processing? Should work without problem.

I'm on driver version 516.94. I'll update to 522.25 and try it again. If that doesn't work, I'll try CPU mode. Thank you!

Thank you ! :D 

cpu mode is super valid and fast, let me know :D
