Description magnamara69 2015-06-20 18:52:47 UTC

Using Wacom Intuos pen & touch small(cth-480) with middle click mapped onto side button, running krita 2.9.5 on windows 8.

Changing from krita window to any other window results in the middle click button losing its functionality(i.e. not panning canvas), and must use eraser side of the pen in order to recover it.

Reproducible: Sometimes

Steps to Reproduce:
1.pan the canvas on krita window.
2.switch to any other window.
3.attempt to pan the canvas on krita window using middle click mapped to the tablet
4.if lost functionality, use the eraser tip, then switch back to primary tip.



Windows 8.1.
Krita 2.9.5.
Wacom Intuos pen & touch small(cth-480).
Middle click mapped to side button closer to eraser tip.

Hi,

I'm sorry, I haven't been able to reproduce this yet :-(

I just realized it is not switching windows that makes the middle click functionality dissappear, it is SAVING the document, i confused the two because i always do something else after saving, but leave krita open.

I can confirm this happens each and every time i save after modifiying my krita document, some information that might be relevant:

1)I have openGL enabled and have an Intel HD Graphics 4000.
2)Autosave every 6 minutes.
3)Create backup enabled.
4)Undo stack size 100.

I can reproduce this , although after some seconds the pen starts to work. 
If i switch to some other window and come back to krita after some brief moment the pen stops working it can't paint or pan then some seconds later it comes back. 

I have noticed that if i take the mouse off the canvas ( for example if I hover it on toolbar) for a moment then it starts working again

I am guessing that this has to do something with the notification or focus bug 

I am on kde plasma 5 linux with latest krita built from git master

For me this doesn't happen anymore in 3.0 latest git with qt 5.6 on linux. Can someone or the reporter check if this happens on windows?
