By chance, I have discovered a quick-fix to the notorious Chrome (Web Browser) issue with some computers, where it simply stops rendering pages, and usually displays blank/white backgrounds without any visible content.
Simply press F12 to open the DevTools menu. This appears to refresh the browser's renderer, and thus restores everything to right. No restart necessary or any crashes happening.
Anyways, it works well for me, so I hope others can enjoy the benefit! Comment and share, if this works for you, too!
