Bug ID: 391346
Summary: [WinInk] Putting stylus on canvas and drawing quickly
can cause a solid mark
Product: krita
Version: git master
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: tablet support
Assignee: krita-bugs-n...@kde.org
Reporter: alvinhoc...@gmail.com
Target Milestone: ---
What can happen is that the EnterEvent is received later than the
TabletPressEvent, which causes KisInputManager to stop blocking one single
mouse event.
Steps to reproduce:
1. Move cursor to somewhere in Krita but outside the canvas
2. Without letting the stylus hover for long, slam (not literally) the stylus
on the canvas area
Possible solution:
Some of the logic handled for QEvent::Enter in KisInputManager::eventFilterImpl
should happen in both QEvent::Enter and QEvent::TabletPress, but only executed
in either one, whichever is earlier, until QEvent::Leave has happened.
