I don't know when this started - maybe it's been there from 1.0, I don't know.
In the histogram, at least now in 1.3.1 for the PC, the clipping indicators in the upper corners don't illuminate soon enough. I can now go to just under clipping according tot he histogram indicator, however if i hover over them ot see the preview areas there is still clipping shown. I need to correct a couple more points down below the indicator level to actually clear it.
