I want to use the “slow down for overhangs” in vase mode. However this appears to be bugged – walls that are “over” the body are not considered as overhang.
Is this known, is it a bug, is there a workaround?
Example model:
Here one of the long sides is printed slowly, the other fast. Relevant gcode:

As you can see the slow speed (G1 F900) is only set to one of the long sides while everything else is printed at high speed (G1 F8315.299).
The settings:
I guess I can slow down the entire print to fix this. But I need to recalibrate extrusion and fan settings as they work in a quite narrow parameter range for my application – so not entirely trivial for me. Also time loss as most of the structure I print is vertical.
