I remember dealing with similar display glitches in browser games on my PC a while back, where parts of the screen would turn solid green or just not render properly in full-screen mode. It drove me nuts until I figured out some lighting and chroma key basics from this guide on https://skylum.com/blog/iphone-green-screen. Surprisingly, understanding even background separation helped me troubleshoot my setup better.

I've experienced similar frustrating display issues with PC games after updates. Just last month, my favorite strategy game stopped responding to the fullscreen toggle completely after a patch. What worked for me was updating my graphics drivers and running the game as administrator. Sometimes clearing the game's cache files or checking the display settings in the config folder helps too. I also found that temporarily switching to windowed borderless mode can be a decent workaround while waiting for a fix. During these technical hiccups, I usually switch to simpler browser-based games that don't have these complications.
