So far everything seems stable, but there does appear to be some visual issues.
1. When viewing the lockscreen the status bar icons aren't positioned correctly. Like there's padding to the left of the carrier name, but padding to the right of the battery icon is missing.
2. If you take a look at Bootleggers or Evolution X you'll see that the status bars height perfectly aligns with the notch. With LOS it's slightly too tall, so you often see a little color under the notch. This is an issue with LOS16 too and an easy way to notice it is by opening the stock messaging app.
