--- Comment #1 from Valeriy Malov <jazzv...@gmail.com> --- So I poked around a bit and it seems to be caused by QApplication::desktop()->screenGeometry() returning invalid, pre-setup geometry for some reason i.e. in XinputAdaptor::mapTabletToScreen initially screenList contains: 1920x1080+0+0 1680x1050+1920+0 which is my "boot" geometry and is incorrect After I restart kded5 screenList contains: 1920x1080+1680+0 1680x1050+0+0 which is my actual geometry, set through KDE screen settings and applied when I log in This messes up coordinate transformation matrix and breaks screen mapping as a result Not sure if it's a Qt bug. I'm using Qt 5.7.1 -- You are receiving this mail because: You are watching all bug changes.
