SUMMARY
My display setup is two 3840x2160 monitors side by side, ie a left monitor and
a right one.


STEPS TO REPRODUCE
1. Open kcolorchooser and select "Pick Screen Color"
2. Move mouse to upper left of left screen and note offsets - 0,0 (correct)
3. Move mouse to lower right of left screen and note offsets - 1919,1080
(wrong)
4. Move mouse to lower left of right screen and note offsets - 3840,1080
(wrong)

OBSERVED RESULT
Both monitor sizes used appear to be 1920x1080 (wrong) with a starting offset
for the right screen of 3841,0 (correct)

EXPECTED RESULT
1. -
2. -
3. 3839,2159 (or perhaps 3840,2160)
4. 3840,2160 (or perhaps 3841,2159)
