Short description of error
using rotate around selection makes zooming with the mouse wheel more and more sensible,
up to a point where hitting a single mouse wheel tick forward would zoom right through the entire mesh.

Exact steps for others to reproduce the error

make sure "rotate around selection" is checked in the preferences

  1. start blender, go to edit mode, subdivide the cube once, so that there is a centre vertex on each side
  2. rotate to front view (freehand, dont use menu/key)
  3. zoom back and forth using mouse wheel just to watch its sensibility
  4. select centre vertex of the cubes front side
  5. freehand-rotate your view 90 degrees to the right around the cube
  6. select the "new" centre vertex (the cubes right sides centre vertex)
  7. freehand-rotate your view back to where you were (in front of the cube)

repeat steps 4 to 7, the effect is accumulative but already noticable after one repetition

  1. zoom back and forth and compare to what zooming was like at step 3

after a couple of repetitions, zooming in will bring the view through and way beyond the cube,
but the opposite is possible as well: if you keep selecting the centre vertex of the back side of
the cube, you end up not being able to zoom anywhere close to the cube

resetting the zoom speed is possible by pressing home key, however i notice that this doesnt always
work: e.g. if i look at the cube from above, it correctly resets, but looking from below it does not

i noticed this behaviour first in sculpt mode, where it is really frustrating, because the distance to
model is actually relevant (dyntopo/ brush size)
i have not tried out other views like vertex/weight paint or so
