  The same: as we multiple by -1 it's also corrected now. Though I admit to not have tested it (yet)

  The cause in the first place is that Qt expects the delta in another dimension. I just verified by looking at Qt code and there it's also multiplied by a negative value: https://code.qt.io/cgit/qt/qtwayland.git/tree/src/client/qwaylandinputdevice.cpp#n557
