I can confirm krdc is affected just the same way that KMail and VirtualBox are: it works on screen 1, but fails to repaint on screen 2. It's a much simpler application than KMail to debug. I can reproduce this by using it to VNC into my Mac machine or to RDP into my Windows one. The trick must be here somewhere: https://github.com/KDE/krdc/tree/master I don't understand how KMail is also affected but the qtwebengine examples aren't. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
