Issue Summary

Alright as discussed i'm raising a single issue since all of these seem to be related to #1164 and the fix should be related as well.

So after testing the latest source code (JAN 22nd 2019) and compiled with Qt 5.12 (the version has no effect in this as previously thought because I compiled it with 5.11.3) I've gathered a list of the tools that are working with a mouse input but not with tablet input:

• Eyedropper
• Polyline
• Smudge / blur tool (test it by pressing ALT)
• Selection tool**

** This one is the most critical in terms of destroying the artwork. In the case of the selection tool the clicks are acknowledged and it creates a selection box, but it also creates a second duplicate selection, so even though you can still create the selection, it is behaving strangely and the results are quite worrying as it completely destroys the drawing, however it works as expected when using the mouse.

Expected Results

Each tool should work in the same way when using both a stylus and a mouse.
