When mac wakes up, Google Chrome and recently realized Brave too (safari was fine) showing weird colors on certain tabs, also recently found out, even if I share my screen with Chromecast same glitchy patterns are visible on the shared screen as well.

As far as I can tell, maybe redrawn sections of the browser window showing this, because some websites are partial others have glitchy squares all over the window.

Only way to fix it, restarting Mac, quitting browsers is not working.

Note: I'm using a USB-C connected external monitor, which runs with DisplayLink, I always had issues with this display on Mac (Asus Zenscreen), after recent updates on OsX it was fine, so I still have my suspects on it.

Is this a fixable issue? Any configurations to fix it?
