Same on my iPhone 7 Plus. Only thing really bothering me I need a fix ASAP!!!
Also seeing this half-screen bug thing... haven’t been able to quantify when it happens
This bug was also in one of the iOS 11 Betas, just this morning deleted my screen shots of this from 29 days ago (VZW 6S+). A workaround that addressed this bug is to turn off or toggle twice "Reduce Motion" - I've turned it off on my 6S+ and it hasn't happened to me since. A bit more drastic is to Reset All Settings, which will leave Reduce Motion off until it's manually enabled. I hope this helps.Well....on this beta, I can’t be on a call and do anything else or I get the dreaded “half black screen” on the right side.
It happens every single time.
This is annoying me the most.
