help on images with higher precision

Dear list,

I have been using gimp for years, and the only feature I miss is the ability to handle high precision (more than 8bit per color) images, because most of my images are black and white : the trouble being with 8bit per color that feathering selections and modifying curves in selections creates step-like zones that are sometimes visible.

I tried the new 2.9 (from yesterday's git) ; unfortunately gimp crashes when : - opening an image ; then
- defining its precision to 16 bit ; then - selecting a zone (with the free select tool) ; then - feathering the selection (with a radius of 300) ; then - calling the curves tool crashes gimp.

I then tried to do the same sequence but staying on 8bit ; gimp crashes on the same step.

Should I revert to gimp2.8 ?

You shouldn't be using 2.9 for production at this point of time for sure :)

Things break easily.
