[Gimp-user] Gimp 2.10-RC1 seems to ignore back- and foreground colour setting

The attached ping says it all.

This is on Debian.

Never mind what colour I select for the painting tool, it does not
change anything.

A perhaps more accurate description is that most operations are now performed
on linear 32 bit floating point data, regardless of which precision
pixels are stored with.
Fast path conversions from storage formats of 8bpc and 32bit float
have been around
in babl for many years, but for most permutation of gray/rgb/alpha in
16bit precision,
both float and integer no such short cuts existed and babl would
roundtrip the data to
64bit floats. As of babl-0.1.46 released earlier this week most gaps
for these pixel-formats
have been filled with fast paths. There is still room for making the
16bit code paths faster with
SIMD but GIMP-2.10rc2 should already be much better than 2.10rc1, for
further details
