This crash cannot happen with that combination of Qt and Krita. There must be something wrong with the tarball the fedora package uses or something like that. The 4.1.7.101 tarball explicitly works around a dumb bug in Qt 5.11.3 and 5.12 that causes a double deletion. We have a workaround, it is in 4.1.7.101. // See https://bugreports.qt.io/browse/QTBUG-72488 #if QT_VERSION < QT_VERSION_CHECK(5, 11, 3) if ((event->type() == QEvent::MouseMove || event->type() == QEvent::TabletMove) && (!d->matcher.supportsHiResInputEvents() || d->testingCompressBrushEvents)) { d->compressedMoveEvent.reset(new Event(*event)); d->moveEventCompressor.start(); /** * On Linux Qt eats the rest of unneeded events if we * ignore the first of the chunk of tablet events.
