Hello @tiar,
I remember some time ago you said you would be away for a short time (Welcome back btw), so I’m not sure you saw this post:
When you said the modifiers state are a bigger issue I remember this post (and others similar with ‘stuck keys’). However it seems that under Windows 10, using a tablet (not a mouse) and pressing crtl, shift or alt always give this error log.
It really is a problem with one individual sytem or it is a Qt problem?
