gimp-2.99 screen color picker shows totally wrong colors
This is with babl/GEGL/GIMP-2.99 from git updated this morning, on Gentoo Linux.
Notice the color "Lemon Yellow". Previously GIMP color-picked this color as having the LCh hue "95", which I entered into the spreadsheet. Then I color-picked several more colors, still with believable results.
Then suddenly GIMP started color-picking the wrong colors. For example, going back to "Lemon Yellow", instead of color-picking yellow, the picked color shows a strongly magenta color.
The workaround (which I've used already several times this morning) is to restart GIMP-2.99, at which point I can color-pick several more colors before the screen color picker loses its ability to pick the screen color.
