I've had this issue for a long period that it never bothered me. But for whatever reason, as of lately, it's been bothering me and prompting me to research. Low and behold.... there are tons of claims with this LCD being funky. Not one thread has taken me to an actual issue/remediation.
Appears to be a hit or miss thing. Did you get your unit replaced or what was the end resolution on this thread? @farshadatis
