OnePlus 3T UI errors

I have been experiencing issues with the UI moving around by itself. At times the device is barely usable. Not sure if the problem is related to this issue or not.

Can you try to got to Settings>>Apps & notifications >>See all apps >> Bliss Launcher >> Storage >>Clear Storage + Clear cache and see if it solves your problem

See under your error 7 post

As discussed previously in the Telegram group, this error was not caused by the previously mentioned install problem. I tried original and newer versions of stock firmware and was unable to fix the issue. Eventually I installed LineageOS+MicroG which ran perfectly. Sorry I never obtained a log file on this one, I was configuring this handset for a friend and it was already overdue.

I have exaclty the same problem as you mentioned as of december 5th.
Is there any work done on this distrib to have it work on Oneplus 3/3T?
Any other recommendation, advice or idea?
Thanks in advance, cheers from France,
