iMac 2010 Graphic Driver Issue

Hello Everyone, recently I acquired a iMac 2010, with AMD graphics and intel i3 as processor, i upgrade their ram to 8gb.
i tried to install Fedora 38, but I have a problem with the graphic drivers, it shows a 4 layered screen and all is glitchy, i’ve tried everything to get work, please help

Did you try adding nomodeset to the kernel command line? That disables a lot of advanced graphics features. But it would be more usable than what you are showing in your screenshot.

yes, i tried that line, but the problem of the safe graphics mode is the laggy performance of the system, and i need the entire graphic performance 'coz my work need it :c

If it worked previously, another option is to install an older kernel until the problem gets resolved upstream.
