try the following:
- create a new patch
- create any node (eg. a renderer)
- select the node and enable debug mode for this node
- click anywhere else in the patch and turn and enable global debug mode on and of (i.e.: click the debug mode switch twice) --> tick count for the node disappears
- now click and drag the node a bit --> tick count is back again like when debug mode is on for this node.
i guess this is not expected. also this behaviour is different from b27.1
