After using the trackpad for drawing sometimes there is a safe_assert + crash. This does not seem to happen ever using mouse or stylus. Video of when it happened: https://drive.google.com/file/d/13Z4DWgDs_l6Y0zkDovb0ekDRrB8pcEyV/view I was testing the undo response time as it was very slow after using trackpad, but weirdly not after using the stylus. Do we compress events on trackpad events?

It can be reproduced painting with the trackpad.

SAFE ASSERT (krita): "!m_d->readyShortcut" in file /Users/daedalus/developer/krita/repos/master/krita/libs/ui/input/kis_shortcut_matcher.cpp, line 790
