Can you help how to solve this problem of mine which is a bit annoying, because when I zoom out on the artboard, the details become stripes or lines like on the right side, but the details SHOULD BE on the left side. Thank you.
GPU Performance has been an unreliable feature for many ever since it came out. If it is giving you problems then you can turn it off altogether in the Performance section of your Illustrator preferences (aka settings).
you can try and turn off the Real time preview in the preferences. You can try updating the driver for your card. Or if you do not already use the Studio driver, do that. But that's basically it.
