If the button is clicked then the raster colormap disappear. It is not possible to recovery not even from the raster properties, style tab, because the gray band is "lost".

Doing the stretching with the raster properties, style -> contrast enhancement -> stretch to min/max works correctly.

Tested on trunk on both Windows and Linux.

Does master work for you?

I have opposite problem in master, stretch to full dataset works but local stretch does not.

Use of float for min/max values was causing problems with Float64 datasets, especially if no data value was set to an extreme value.

Fixed in d52ada5 (master).
