Description Camila Paschini 2016-05-30 14:59:23 UTC

Although Krita will randomly appear to have switched into a light color schemed interface, it seems to run fine, until I try to use my Wacom Bamboo Touch tablet, which I realise is quite old by now, and only partially supported by Wacom themselves. When I hold the stylus and place my hand on the tablet's surface to draw, the canvas will zoom in and that makes it completely impossible to use krita. If I do not raise my hand again, and keep on drawing, the canvas will remain on the current zoom level until I do raise my hand and place it back on the tablet's surface. I thought at first it could be the touch function of my bamboo acting up, but the problem persisted when I turned the touch off. On top of that, there is absolutely no crosshairs on the canvas to show where on the drawing my pen is hovering over.

Im running Mavericks Beta 10.11.6 (build 15G7b)

Reproducible: Always

Steps to Reproduce:
1. open a document to draw on
2. hold stylus 
3. place hand on the tablet, hovering the stylus over it.

Actual Results:  
The canvas will zoom in, as if I had pressed the zoom in button once.

Expected Results:  
I should see the crosshairs hovering over the canvas.

This could be tablet related and not Krita code related, however, this problem doesn't happen when I use my Bamboo on my Windows computer running Krita 3 RC1

I think that both issues might have been fixed in the final release -- that's for tomorrow. If you go to files.kde.org/krita/3/osx, you can already download the dmg to test, though!

Thank you for the info! I have just downloaded the  krita-3.0.dmg version form the address you gave me and the bug is still happening.

I'd also like to add that the current recommended version from he downloads page, version 2.9.11 (git 1c398ed) works smoothly, without any of the problems reported here.

I have the problem with version 3.0, (git f0cbffc)
I have a `wacom intuos 3 A5`
System infos: `uname -a` gives `Darwin rvions-MBP 15.4.0 Darwin Kernel Version 15.4.0: Fri Feb 26 22:08:05 PST 2016; root:xnu-3248.40.184~3/RELEASE_X86_64 x86_64`


problem details:
When I approch my pen towards my tablet and enter the hover zone (~1cm above the tablet surface), canvas __zoom out__
I tried many things, many drivers versions, many tablet configuration, and nothing works, so I think krita misunderstand some table signals. I tried to tweak/delete shortcuts, but nothing worked (the bug is still present when I delete all shortcuts that krita allows me to delete in pref > canvas input settings > Zoom canvas)

The problem here is a bug in QT5 which reports a 'tablet enter' event as a 'scroll wheel' event. The only thing you can do is remove the default canvas input zoom settings in the settings until we have fixed it.

I think this is fixed in 3.1 beta; I can no longer reproduce it with my Intuos 3 on my macbook with a clean config and clean install.
