Regarding QR Code Recognition Accuracy

After updating to v83, the QR code recognition feature started performing worse than it did on v78—for example, it no longer recognizes from a distance of about 50 cm, it fails when the QR code is angled around 45°, and it also stops recognizing when the code is even about 10 cm away from the center of the view; if anyone knows how to fix this, please let me know.
