I found that transparent stripes appeared on the display on half the screen like from a barcode, like a fingerprint after using the catima application. After turning off and rebooting, nothing changed.
Android 14, FP5.
After a couple of hours, the artifact in the form of a barcode disappeared (there was no way to take a photo), then I noticed some faintly visible stripes at the top and when turning on the right side of the screen, maybe this is normal, they do not interfere, probably the screen just overheated.
