Issue description

When enhanced resolution is enabled, parts of the background get corrupted.
The games I've noticed it happening with so far are Destruction Derby and G. Darius, but there most likely even more games affected by this.
Tried and happens on both Windows 11 and Steam Deck, and the first bad commit is c296224

Step-by-step reproduction and logs

Have default settings and only enhanced resolution enabled, load an affected game, and wait until you reach a point where you'll notice the corrupted graphics.

Thanks for taking your time to bisect this, should hopefully be fixed now.
