I just stubled over a little bug in 27.2 when renaming a node. It is not really important as you are probably not supposed to rename a node this way.
however, here we go.
try this:
1.) produce a new node (like ‘Quad’)
2.) open an Inspector window and give the node an arbitrary descriptive name
3.) double click the node, change the descriptive name in the patch (not the inspector) and hit enter.
4.) the node will stick on the upper left corner and will be rather fucked up…
