thanks for reporting.
The shifting problem is interesting. Is there some common action that you typically performed before it happened? I have heard about it from one other user, but we were not able to identify what went wrong.
The problem with the node monitor has been tackled, however I do not know yet when the next release is due (see also this thread).
I tried to reproduce the problem with the Create Date&Time Range node, but failed. If you could provide a minimal example workflow, that would help a lot.
It does seem to happen sporadically. I notice that it only seems to be with the first open workflow. If there is only one open workflow and this behaviour occurs, opening another workflow brings the screen back to normal - but only for the second workflow. Return to the first one and it jumps back to the weird shift.
My only workaround for now is to have a dummy workflow open as the first tab and everything else is opened after this one…
