#2212: Map display fails to display top layer if 29 or more layers are in the
list

I created 48 raster layers for an animation. The top layer is the land
boundary and all subsequent layers are time interpolated rasters
(evolution of temperature in time)
I activated the fist layer (land boundary layer always on top) + and one
by one (kept only one temp map active display) therefore I has active for
display on the mam only 2 layers at a time: top + one of the 2nd , 3rd,
... etc until 48.
By the time I reached the 29 layer the land boundary in not displayed
anymore. Therefore if between the 2 layers in the list are 29 or more
items the first layer (top layer) is not displayed.
I tried this several times and it is reproducible.
The workaround was to move the land boundary layer after the 29 position
in the list and I could display the rest of the layers on the map for
saving to disk.
Not catastrophic bug, but I think it needs to be addressed

Hi,
which tool are you using to make the animation? just individual save
screen as image?
(so is it related to just the layer list, or one of the animation tools?)

Hi
I am saving maps as PNG and animate with mencoder.
I believe that the animation tool you are pointing tool deals onlu with
individual layers. I need to animate multiple layers. Saving maps from the
display manager as image files just does that.
Now irrespective of what I am using the bug is valid. If two layers in a
list are separated by more than 29 items the display manager gets confused

I don't have exact numbers but I can confirm that I experienced something
like that several times.
