Mirror images more resemble being flipped inside out. Sort of.
Imaging holding your hand out flat, parallel to the ground while facing a mirror. The tips of your fingers would be closest to the mirror.
Now imagine if you were wearing a glove on that hand and you took the glove off so it were inside out.
If you were to compare the inside out glove to the reflection of the hand the glove came from, they would look similar.
Mirrors just show us what they see.
If you target the lowest common denominator, you’re likely to catch more fish. Its great to see developers make games with the Deck in mind.
Take it from me. I had the exact issue. I got my deck, and it immediately had that problem. It’s a problem with power delivery to the GPU I believe. It can even be checked if you look at the kernel logs you’ll see GPU error. Sorry to hear it’s still an issue with decks. RMA that poor thing.
