There are a number of lines that division by zero could happen in frameworks/kwindowsystem/src/platforms/xcb/kwindowsystem.cpp if displayGeometry returns a 0 QRect. I think that is what is happening with bug 349512.
viewportToDesktop, viewportWindowToDesktop, desktopToViewport I’m not clear on the best way to prevent this. Forcing displayGeometry to never return a 0 QRect (which seem the best) or by checking all the locations of division by 0. Any suggestions or comments?
