The following bug report has been submitted:
Platform:        macOS-14.5-arm64-arm-64bit

Description
Default thresholds in projection mode give ""hot pixel"" appearance with EM maps.

Hi,

When I use the projection display in the Map toolbar, it looks good except that there are some ""hot/white"" voxels - even in cases where the map is symmetric and they shouldn't be there. I suspect this is some artefact, as reducing the last (right most) threshold in Vol viewer removes them. Would it be possible to adjust the default thresholds so that this doesn't happen? As an example, try EMD-9118.
