Just try painting with a 100px brush :) sRGB, Adobe RGB and other profiles work ok with 16bit-int, but scRGB alone doesn't :(
Happens with the openGL canvas only.
Git commit d97b77ea4e96b29cc74eab1ca49db8cf2cdfecd7 by Dmitry Kazakov. Committed on 20/02/2014 at 19:07. Pushed by dkazakov into branch 'master'. Move the cs-conversion of the openGL texture tile into the scheduler thread Otherwise it blocks the UI on conversions of some complex color spaces like scRGB 16 bit integer.
