Plane 4.1 stable

Everything have been working ok on 4.0.9. I have multiple OSD screens which i change in flight with a slider on CH 10.
Today i´m trying 4.1.0 and this control does not work anymore. The CH10 its being read perfectly by the controller and i can even change between OSD screens if i change the OSD_SW_METHOD from (1) PWM to (0) RC change.

I tested your parameters, and the issue seems to be the overlapping channel ranges. These are the params:

OSD1_CHAN_MAX    1300
OSD1_CHAN_MIN    900
OSD2_CHAN_MAX    1700
OSD2_CHAN_MIN    1300
OSD3_CHAN_MAX    2100
OSD3_CHAN_MIN    1700
OSD4_CHAN_MAX    2100
OSD4_CHAN_MIN    900
OSD_CHAN         10

notice that there is lots of overlap, especially OSD4 covering the entire range. When I fixed your overlap so that each channel has its own range it worked correctly.
I also tested your parameters with 4.0.9 and it behaves badly there too, cycling constantly between screens.
