Issue:
It seems that with my configuration I get the following warning (but treated as an Error):

You can clearly see this in the source code of 6.4.3 (see: https://codebrowser.dev/qt6/qtbase/src/testlib/qtestmouse.h.html , line: 200) that There is a potentially uninitialized local variable 'meType', as it's not assigned on the default clause in a switch case (which causes the warning in my case).

I'll add temporarily an extra ignore warning flag in this case as a workaround, but I suppose this shouldn't be done explicitly.
