Weird Corruption on PC screen after playing Chi No Rondo in TurboEngine?

So, I was playing Castlevania Chi No Rondo in TurboEngine (I usually use ootake for TG16, but It won't load cues of CD games from anywhere besides a disk drive) and it was fine. Then, right before I exited on the menu screen, something strange started happening with my computer, whenever I did something that used visual effects (like minimizing a window) I got a ton of corruption on my PC screen.

This is what happens when I minimize a window:



I'm not sure if the game itself caused the error or if it was something else, but I'd really like to get it back to normal. Any ideas?

Thanks.

Edit: was able to fix by wiping the screen with turboengine's window (?)
