Change Threshold settings for Advance War Dual Strike - how?

Got a problem with the cursor in Advance War Dual Strike, which is invisible. A solution would we to change the threshold in “3D- Settings” I’ve read somewhere. Can’t find this option in the core-video setting or anywhere else (ios version)?
