Scale mask: 42f788ffe26d67864d569c3a3044619d49fc693a (qtbase/5.6, 10.2.2016, 5.6.1)
Description
Drag and drop shaped pixmap window doesn't respect HiDPI scaling, so the the pixmap is e.g. small and clipped.
Several aspects here:
- QShapedPixmapWindow is clipped if the DnD pixmap has a mask since QWindow::setMask() does not scale the mask (as opposed to QWidget::setMask()). This is the case for item view DnD (
QTBUG-46068) but not for tests/manual/highdpi. To reproduce: Use example fromQTBUG-46068with scaling. - QShapedPixmapWindow has the wrong size if the pixmap has a DPR != 1. To reproduce: Apply https://codereview.qt-project.org/#/c/148747/ , drag text with scaling, note white border around DnD window.
