Visualization Problem Illustrator CC

[christianc62726725]

Hello. Im working with this file in CMYK mode, the background is a green gradient but it appears as black. When Im change the file to RGB the background looks good. Its not the first time that this happens to me (My colors are in CMYK mode) Why this happen??

Btw I have installed the latest version of Illustrator (2020)

Can you please show the "good" version?

Which colors did you use?

Does it get better when you View > Preview on CPU?

Yes, its solves when I change the preview to CPU

As Monika already sort of hinted at, this most likely is an issue with your graphics hardware. Update the driver and configure it suitably.
