Whenever a regular QWidget contains a child render-to-texture widget (like a QOpenGLWidget) that is opaque (attribute Qt::WA_OpaquePaintEvent is set) and completely covers the parent geometry, the child widget would not be shown. This happens because QWidgetBackingStore::doSync contains a check to see if an opaque child completely covers its parent, in which case it does not draw the parent, and only draws the child. This is an issue if the widget is actually a texture-based one, because for it to be seen on screen, the parent widget has to be redrawn with a proper blending mask, so that the rtt widget gets properly composed into the place where the mask is. The fix consists in keeping the parent widget being marked dirty, in case it has an opaque texture-based child that completely covers it. This will force a redraw of the parent widget with a proper blending mask.

This directory contains autotests and benchmarks based on Qt Test. In order to run the autotests reliably, you need to configure a desktop to match the test environment that these tests are written for. Linux X11: * The user must be logged in to an active desktop; you can't run the autotests without a valid DISPLAY that allows X11 connections. * The tests are run against a KDE3 or KDE4 desktop. * Window manager uses "click to focus", and not "focus follows mouse". Many tests move the mouse cursor around and expect this to not affect focus and activation. * Disable "click to activate", i.e., when a window is opened, the window manager should automatically activate it (give it input focus) and not wait for the user to click the window.
