Blurry text on Dock. MacOS Sonoma, 2012 iMac 27"

Hi guys, noob here, got Sonoma installed through OCLP. At some point suddenly, around a month ago, the right click menu on the dock started having blurry text, as you can see in the picture. Weirdly enough, the drop down menu doesn't have this blurry issue, and also no issue when right clicking anywhere else. I'm not the main user of this machine, and no one is aware of any configuration change that may have caused this.

If that hints towards anything, I've configured this machine with reduced animations, reduced transparency and high contrast mode. I'm only using the iMac display and no external monitor is connected.

Any ideas? Thanks
