    If you could provide a .3mf file (File > Save Project in Cura) that would really help. From what I can see based on your pictures, those angles look like about 45°? Try increasing the Overhanging Wall Angle to 50 or so.

    Also you might want to play with the Z Seam settings in the Walls category because I really wouldn't want to have my printer start a layer (the white marks you can see in the bottom right corner) on an overhang like that.

    It appears that the speed change only affects the outer walls.

    G1 F3600 X121.031 Y105.758 E95.1551 > current speed of G1 moves
    G0 F7200 X121.031 Y105.778

    G1 X121.82 Y105.079 E95.48507  > These moves are at the last speed  which is 3600
    G1 X108.178 Y105.078 E95.71194
    G1 F360 X122.22 Y104.679 E96.61206  > The speed changes here to 10% which is my setting for Overhang Speed.
    G1 X107.778 Y104.678 E96.85223

    G1 F3600 X108.559 Y124.541 E97.64989 > back to full speed

    This is why things are listed as "Experimental".  It seems to me that the Inner Wall should also be at the reduced speed.  Since the setting only is enforced on unsupported areas I'll take a wild guess and say that it may be because my 45° chamfer allowed the inner walls to be supported by the layer below and so there was no need to change speeds.
