Description Dmitry Kazakov 2014-02-20 18:18:45 UTC 
Just try painting with a 100px brush :)

sRGB, Adobe RGB and other profiles work ok with 16bit-int, but scRGB alone doesn't :(
Comment 1 Dmitry Kazakov 2014-02-20 18:40:24 UTC 
Happens with the openGL canvas only.
Comment 2 Dmitry Kazakov 2014-02-20 19:07:48 UTC 
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.
