The behavior I am seeing under freebsd is as follows:

In the upper half, I get the up-arrow mouse pointer.  Pressing and dragging 
that up-arrow mouse pointer changes the value in gross, non-integral increments.
When moved from the extreme left to the extreme right, the range covered is
large -- If I have the paintbrush tool options up, the size ranges from 1.00
at the extreme left to 1074.55 at the extreme right, although it may be dragged
clear across the screen to get much larger values (9491.50 at my right screen
limit in this case.  Hmmm...  If I test the fuzzy select tool as in your image, 
it goes from 0.0 at the extreme left to 255.0 at the extreme right, where it is 
clamped at that maximum value -- dragging further across the display causes no 
further increase.  

In the lower half, I get the left-right mouse pointer.  Pressing and dragging
that left-right mouse pointer changes the value in small, non-integral increments.
Depending on what the current value is, the possible range varies.  If I type
in the value 500 to set the value, then grab at the approximate location of the
vertical dividing line between the grey and white areas, I get a range of approx
448.56 to 564.11, but if dragged clear across the display it will go up to
approx 1400.

So two thoughts:

1.  Should the integral behavior I am seeing with the up-arrow on the threshold
for fuzzy select be going by tenths, or by whole integers?

2.  It looks like the bug may be tool-related.
