Whenever the stylus enters the active area on the tablet the canvas zooms out.

Reproducible: Always

1. Create a new file
2. lift up the pen about 5 cm above the active area then bring it down to draw
3. canvas zooms out each time

Actual Results:  
Canvas zooms out

Expected Results:  
nothing to happen on the zoom level on the canvas

OS: Mac OS X 10.10.5
Tablet: Wacom Intuos 4 Medium PTK 840

Looks like this is related to touch. Try to edit your kritarc (probably in ./Preferences/kritarc) and add an entry

disableTouchOnCanvas=true

To the main section. If that solves the issue, we can consider making that the default on OSX.

I have the same problem with an Wacom Intuos 3
Krita: 3.0 Alpha (git 854659f)
Wacom Driver: 6.3.15-3
MacOS: 10.11.3

Problem: When getting close (5-3cm) to the tablet, canvas zooms out (around 30-50%)

Added the parameter from above "disableTouchOnCanvas=true" in the file "~/Library/Preferences/kritarc" right above disableVsync=true 

Problem is still not solved. Zoom only happens between 4-1cm .. below 1cm nothing happens. touching the tablet works and you can paint, nevertheless lifting the pen up and trying to paint on a different place results in another zoom out action

Same problem on a Cintiq Companion Hybrid (it identifies as A1300 if that helps).

Krita 3.0 Alpha (git d75b959)
Wacom driver 6.3.15-3
OSX 10.11.4

Wasn't sure where the main section was so added it where previous poster added it above disableVsync=true as everything there has similar formats.  As with previous poster, problem is still occurring.  Did consider adding it to the [MainWindow] bit but that had some rather intimidating stuff in it :)

It's actually a problem in Qt, opentoonz has the same problem.

I could not find this thing earlier!

I wanted to say that I think the problem may have something to do with keys stuck in software (not sure why they're getting stuck or if it has anything to do with the Qt problem) but when the zoom problem happened Krita also acted kind of* like the cmd key was being held down.

* some of the actions were consistent with the cmd key being held down, some of the things I could do when the bug was bugging I couldn't do with the actual cmd key held down

I investigated this earlier and found a hacky workaround is to go into the settings and remove the mouse wheel shortcuts for canvas zoom. Somehow, the tablet "active" events are being picked up as mouse wheel events.
